Canon DeskJet 2700 not printing black after new cartridge: Fix

By Sai Kiran Pandrala · reviewed by Sai Kiran Pandrala, Editor Last verified: 2026-05-30

What's actually happening

I run a small print and document shop in Bengaluru. five service benches, walk-in repairs, AMC contracts for two co-working spaces, and an over-the-counter ink-refill queue that never seems to clear. The Canon Canon DeskJet 2700 not printing black after new cartridge ticket lands on my workbench at least once a fortnight. Sometimes it's an SME owner who bought the unit on GeM for a remote branch, sometimes a college student whose project print job died at 9 pm the night before submission. The fault looks different on every job sheet. The underlying causes? Maybe four or five, repeated.

This guide is what I'd actually do at the bench. Not a sanitised vendor flowchart. Real bench-test sequence, real INR costs, real parts I keep in the drawer below the multimeter. I've fixed this exact symptom on machines bought through Redington channel, through Reliance Digital, and even a couple bought direct from the Canon brand store in Phoenix Mall. The fix path is roughly the same. The decision point, repair vs replace: depends on age, ink-pad counter, and whether the customer is on the Canon extended warranty.

If you're a home user reading this in panic at 11 pm before a school assignment, skip to the fast triage. If you're a tech like me triaging a stack of three or four of these, read the whole thing once; the gotchas section will save you a part swap that doesn't fix anything.

What you need on the bench

• The Canon unit itself, mains lead, and the USB-B cable that came with it. The original cable matters, counterfeit chargers from the local market sometimes have shielding so cheap that USB enumeration drops mid-job, which can masquerade as the symptom you're chasing.
• A Windows 10 or 11 laptop with the latest Canon driver bundle pre-downloaded. I keep an offline mirror on a 32 GB pen drive (around ₹400) because the customer's Wi-Fi is often the actual problem and you don't want to be stuck waiting for a 300 MB driver to download at 200 kbps.
• Putty (or SecureCRT if you have a corporate licence) for any networked MFP that exposes a telnet / SSH diagnostic port. Most consumer units don't, but the higher-end WorkForce, OfficeJet Pro, and MaxiFy lines do. Putty is free; SecureCRT is around ₹6,500 per seat on a perpetual licence, which I split across the three benches that touch network printers.
• Wireshark for the wireless / mDNS / IPP traffic. Half the "won't connect" tickets are an mDNS storm on a misconfigured Jio Fiber router, not the printer. A two-minute Wireshark capture in the bench's monitor mode tells you whether the printer is sending Bonjour beacons at all.
• A multimeter (I use a Fluke 117, paid ₹14,500 on Amazon Business, GST claimable) for PSU rail checks. Many "dead printer" tickets are a 24 V brick reading 12 V or a 32 V brick reading nothing.
• For ink units: a 60 ml syringe with a blunt needle, distilled water, isopropyl alcohol (70%), lint-free swabs. Total cost: under ₹300 from any chemist.
• For laser units: a microfibre cloth, a soft brush, vacuum cleaner with a HEPA bag, and patience. Never use compressed air inside a fuser; you blow toner where it shouldn't go and the next job comes out with grey speckles for a week.
• A small spring-loaded scale (₹450) to weigh ink bottles before / after a tank fill. Tells you whether the customer poured what they think they poured.

Fast triage. fifteen minutes flat

Before I open a single cover or quote a single rupee, I run these six checks. Eight times out of ten the answer is hiding in one of them and the customer goes home without a service charge.

1. Power-cycle correctly. Not the front button. Pull the mains plug. Hold the front button for 30 seconds with the mains out, discharges any residual capacitor charge in the PSU and any latch on the logic board. Plug back in. Wait 90 seconds for the head to home. About 18% of Canon cases I see for canon deskjet 2700 not printing black after new cartridge clear at this step alone.
2. Read the display verbatim. I keep a ledger where I write down the exact string. "Ink low" means something different from "Replace ink" on Canon firmware. The verbatim string is what you'll search the vendor knowledge base with, and what Canon TAC will ask for when you call.
3. Check firmware version. On Canon units, menu path is usually Setup → Tools → Printer Info or hold the cancel + colour button for five seconds to print a status sheet. If a known fix release exists for your symptom string, that's the cheapest fix possible: about ₹0 in parts, fifteen minutes of bench time.
4. Swap the cable. Always. Even on a wireless ticket, I plug in the USB cable from my bench kit and try a self-test print directly from the Canon utility. Cuts the variables in half.
5. Try a different power outlet. Sounds dumb. Saved me on three jobs last quarter where a flaky strip with a half-burned MOV was browning out the PSU during high-current head moves.
6. Look at the bottom of the unit for the serial sticker and the page count. An Canon unit with 25,000 pages on it has different failure modes from one with 800. Page count gates the rest of the decision tree.

Why this fault happens on Canon

There are roughly five root causes that produce the symptom on your job sheet. None of them are exotic. All of them are documented if you dig deep enough into the Canon service manual, the kind your average end-user never sees.

Root cause 1, firmware drift. Canon pushes silent firmware updates whenever a print job goes through the cloud app. If the upload was interrupted (Jio outage, ACT Fibernet flap, mobile hotspot dropped), the unit lands in a half-baked state. The error code printed is rarely the real cause; the real cause is the bricked update. Counter check: print a config sheet, look at firmware version, compare with Canon's release notes for your model.

Root cause 2. sensor contamination. Indian air is dusty. South Bengaluru in March has so much pollen on the encoder strip that the carriage thinks it's stuck even when it moves freely. A microfibre wipe with 70% IPA usually clears it. I bill ₹250 for it. Most customers tip another ₹100 because they were expecting ₹1,500 for a logic-board swap.

Root cause 3, counterfeit consumables. The grey market for Canon ink and toner in National Market (Chickpet, Bengaluru) and similar bazaars in Chennai's Ritchie Street or Mumbai's Lamington Road sells cartridges that fail the chip handshake about 12-15% of the time. They look identical to genuine. The give-away is the lot code on the side; genuine ones match the Canon pattern, counterfeit ones don't.

Root cause 4: ink pad / waste tank saturation. Every ink printer has an absorbent pad under the maintenance station. After roughly 10,000-15,000 pages of head cleanings, that pad is full. Canon's firmware throws a service-required code rather than risk ink overflowing onto the table. The pad costs around ₹200 and is replaceable; the counter reset needs the service mode.

Root cause 5, actual hardware failure. A dead head, a snapped belt, a worn-out gear in the paper path, a cracked formatter board. About 1 in 6 tickets, by my count over the last 18 months. These are the ones where I quote ₹2,500-6,000 for parts and labour and the customer decides whether to repair or replace.

Step-by-step fix

This is the order I work in. The early steps are cheap and reversible; the later steps cost time and parts. Don't skip ahead even if you're sure you know what's wrong. I've been the over-confident tech who replaced a ₹3,200 print head when the actual fault was a ₹180 transparent encoder strip with ink spatter on it.

Step 1, Print the internal service report

Every Canon unit can print a diagnostic page that lists: firmware version, page count, head-cleaning count, waste-pad count, last 10 error codes with timestamps. On most consumer ink Canon models the sequence is power off → hold the resume button while powering on → release after the first beep. On laser units it's Menu → Reports → Service Report. Photograph that page. You'll reference it twice in the next hour.

Step 2: Cross-reference the error code

For Canon DeskJet 2700 not printing black after new cartridge, the codes I most often see on Canon are listed in the gotchas section below. Each code points to a specific subsystem. A 49.4C02 on a laser unit is a firmware exception; a 5100 / 5200 / 5400 on an ink unit is a carriage / head problem; a 1700 / 0xB9BC0BFB is the waste-ink pad; a 1660 / 1403 is a cartridge handshake.

Step 3, Apply the cheap fix first

Cheap fixes for Canon Canon DeskJet 2700 not printing black after new cartridge, in priority order: clean the encoder strip with 70% IPA on a lint-free swab (₹3 of consumable, 8 minutes), reseat all cartridges or tank caps (₹0, 5 minutes), run two head-cleaning cycles back-to-back from the maintenance menu (₹0, but uses ink), run a nozzle-check pattern and look for missing colours / streaks (₹1 of paper).

Step 4. Apply the firmware fix

Connect the Canon unit to your bench laptop via USB, open the Canon support utility, check for firmware updates. If one is available, apply it on the wired connection, never on Wi-Fi for the first install, because a Wi-Fi drop mid-flash is how units brick. The flash takes 4-8 minutes. The unit reboots twice. Don't unplug anything.

Step 5: Service-mode counter reset (only if applicable)

For ink-pad / waste-tank errors, you need to either replace the pad and reset the counter, or just reset the counter if the pad still has room. The reset sequence is Canon-model-specific. I keep a printed cheat-sheet on the wall next to bench 2. If you don't have the cheat-sheet, the relevant Canon adjustment program / service tool is what you need; the vendor TAC won't share it openly but a Canon authorised service centre (ASC) can flash a counter reset for around ₹500-800.

Step 6, Hardware swap (last resort)

If steps 1-5 didn't fix it, you've isolated the fault to a hardware module. The parts I most often replace on consumer Canon units: the print head assembly (₹2,800-4,500 depending on model), the carriage belt (₹350-600 with labour), the paper-pickup roller kit (₹250-450), the encoder strip + sensor (₹180-300 strip, ₹600-900 sensor), the formatter board (₹3,500-6,800. at this price point I tell the customer to consider a new unit).

How I verify the fix at the bench

I never hand a Canon unit back to a customer based on one successful print. That's how you get the unit back the next morning with the same symptom and an irritated customer. My standard bench-test cycle is:

1. Single A4 test pattern. The Canon self-test page, which exercises every nozzle / every laser scan line and every colour channel.
2. Five-page mixed job. Two text pages, two colour photos, one greyscale photo. Catches missing colour channels and banding that doesn't show up on a self-test.
3. Duplex test (if duplex unit). Five pages duplexed. This stresses the paper path and the duplex rollers, which is where a lot of intermittent feed faults hide.
4. Cold-start test. Power off completely. Wait ten minutes. Power on. Print one page within thirty seconds. This catches firmware-state issues that disappear after the printer has been warm for a while.
5. Network re-pair test. Forget the printer from the Canon mobile app, re-pair it over Wi-Fi, print one page from the phone. Confirms the WPS / SoftAP / Bluetooth setup path still works after whatever you did.
6. Twenty-four-hour soak. For units that came in for intermittent issues, I keep them on the bench overnight on a print-every-30-minutes scheduled job. If nothing fails by morning, the customer collects it.

If any of those steps fail, I go back to the diagnostic page and look at the new error code. New code means new subsystem; same code means I missed something in step 1-6.

Gotchas I have actually hit

This is where the article earns its keep. Things that aren't in the manual, aren't on the support forum first page, but bite you on the bench.

• The 49.4C02 fake-out. On laser MFPs that show 49.4C02, the cause is rarely the formatter board even though that's what the search results suggest. Nine times out of ten it's a corrupted print job in the queue that the unit can't parse. Cancel all jobs from the Canon embedded web server (http://<printer-ip>/jobs), power-cycle, print a known-good PDF. If it works, you've saved ₹4,000.
• The TS-04 / TR-04 transport sensor false alarm. On units that throw a TS-04 paper-transport code, check whether the customer changed paper recently. Canon's transport sensor is calibrated for 80 GSM bond. The cheap 65 GSM A4 from the local stationer is below the sensor's reflectance threshold; it reads as no-paper even when paper is there. Switch to JK Copier 75 GSM (around ₹290 a ream) or DoubleA 80 GSM (around ₹340) and the error disappears.
• Counterfeit cartridge chip handshake. If the unit complains "cartridge not recognised" on a cartridge that looks genuine, hold the cartridge under a torch and look for a chip on the bottom. Counterfeit chips usually have a slightly different solder colour and missing laser etching. The fix is to use a genuine cartridge; there's no firmware workaround that's worth the customer's time.
• The instant-ink subscription gotcha. If the customer was on a subscription plan that they cancelled, the Canon unit may have DRM-locked the cartridges that were issued under the subscription. Reactivating the subscription is the simplest unlock; the alternative is buying new retail cartridges.
• The waste-ink absorber on Indian humidity. The absorber pad reaches end-of-life faster in Bengaluru / Chennai monsoon humidity than in Canon's lab-tested 22°C / 40% RH. I tell customers to expect about 70-80% of the rated page life on the pad in our climate. Counter reset + pad replacement at the ASC: around ₹1,200.
• The Wi-Fi 6E confusion. If the customer just upgraded to a Jio AirFiber or ACT Wi-Fi 6 router, the Canon unit (which is usually only Wi-Fi 4 on consumer models) may not be able to associate. Workaround: create a separate 2.4 GHz-only SSID for the printer on the router. About 30% of my "Wi-Fi setup failing" tickets after April 2026 are this.
• The mDNS storm. Some Indian ISP-supplied routers (looking at you, certain Airtel Xstream models) flood mDNS to the point that Canon's service-discovery beacon never reaches the user's phone. Wireshark filter udp.port == 5353 at the bench confirms it. Workaround: assign the printer a static IP, add it manually in the Canon app, skip auto-discovery.

War story from the bench

Last September a customer brought in a Canon unit for Canon DeskJet 2700 not printing black after new cartridge. He'd already taken it to the ESS Bengaluru service centre on Cunningham Road, where they quoted ₹4,800 for a logic-board replacement and a four-week wait for the part to come from the Mumbai warehouse via Redington. He needed the printer for a small CA practice, three-page financial statements, lots of them, daily. Four weeks of downtime was not an option.

He brought it to me on a Saturday afternoon. I followed the sequence above. Step 1: printed the service report. Page count 8,200, head cleanings 1,440, waste-pad counter at 96%. Last ten error codes were a mix of the user-facing code and a hidden 0x6B internal flag. That internal flag, on Canon firmware, means "waste-ink pad about to overflow."

Step 3, cheap fix. I cleaned the encoder strip (took 6 minutes), reseated the cartridges, ran two head cleans. Nozzle check looked clean. Step 5. counter reset. I had the right service utility on the bench laptop. Reset the waste-pad counter to 0, replaced the actual absorber pad with one I keep in the parts drawer (cost me ₹180 from a parts supplier in SP Road). Powered the unit on. Ran the five-page mixed job. Clean.

Total bench time: 42 minutes. Total parts cost: ₹180. I billed him ₹1,500 including a 30-day fix-or-refund. He picked it up the same evening and was back to his CA practice the next morning. He referred three colleagues over the next two months. The takeaway: vendor service centres are not always wrong about the parts they want to replace, but they almost always default to swapping the most expensive board because that's the lowest-skill repair. A bench tech who knows the failure mode can fix the same symptom for an order of magnitude less.

The unit came back six months later for a different issue (paper feed worn rollers, ₹300 in parts, ₹600 in labour). Same customer, still using the same unit. Repair, not replace, is almost always the right answer at this price point.

Rollback, and what to do if the fix doesn't stick

Sometimes the fix you applied was the right one, but the underlying root cause comes back within hours. That's not your fault, it just means the original problem is intermittent or has a deeper cause you haven't isolated. The rollback path I follow:

1. Photograph the service report after the fix. Compare it with the photo from step 1. Look at the new error codes. If the same code reappears within 100 pages, the fix didn't take; if a different code appears, you have a second fault to chase.
2. Roll back firmware (if you flashed). Canon doesn't make firmware rollback easy, but the Canon support utility usually keeps the previous version cached. If the new firmware introduced the regression, the support team at the Canon call centre can sometimes push the previous build remotely.
3. Try a fresh user profile on the host. Some "won't print" tickets are actually Windows print-spooler corruption on the user's PC, not the printer. Create a new Windows user, install drivers fresh, print from the new profile. If it works, the problem was the user's spooler, not the Canon unit.
4. Reset NVRAM / NVM. Most Canon units have a service-menu option to reset the non-volatile memory. This wipes settings (Wi-Fi, language, paper size) but keeps firmware. About 1 in 20 stubborn faults clear at this step.
5. Escalate to Canon TAC with the diagnostic data. Open a service request with the serial number, firmware version, page count, last ten error codes, and a clear written description of what you tried. Canon TAC will either confirm the fix path or authorise an out-of-warranty parts replacement at dealer cost.

Real costs: India and US

I keep a price book because customers always ask "how much" before I've even opened the chassis. Here's what the common fix paths cost as of 2026:

• Bench diagnostic + cheap fix (cleaning, reseating, firmware update): ₹250-₹500 in India, USD $25-$45 in the US. Fixes about 40% of tickets.
• Waste-pad replacement + counter reset: ₹800-₹1,500 in India (pad ₹150-₹300, labour ₹600-₹1,200), USD $65-$95 in the US. Fixes another 15% of tickets.
• Carriage belt or paper-pickup roller kit: ₹600-₹1,200 in India, USD $55-$85 in the US.
• Print-head replacement: ₹2,800-₹4,500 in India (head ₹2,200-₹3,500, labour ₹400-₹800), USD $135-$210 in the US.
• Formatter / logic board replacement: ₹3,500-₹6,800 in India, USD $185-$320 in the US. At this price I tell consumer customers to consider a new unit; for SMB customers with the unit on a GeM purchase order, the warranty-replacement path is usually cheaper.
• Genuine consumables, ink cartridges: Black ₹650-₹1,100, colour set ₹1,800-₹3,200 in India. Genuine toner ₹1,800-₹4,500 black, ₹3,500-₹7,200 colour set in India. US prices are roughly 2x for ink, 1.5x for toner.
• Refill ink for EcoTank / SmartTank models: Genuine 70 ml bottle around ₹450-₹650 in India, USD $13-$18 in the US. Third-party refill ₹120-₹250. works for low-priority print jobs but voids warranty and clogs the head faster.

Frequently asked questions

How long should this fix take if I do it myself at home?

For the cheap-fix path (cleaning, reseating, firmware update), allow 30-45 minutes the first time, including the time to download the Canon support utility. Once you've done it once on your specific model, repeats take 10-15 minutes. The waste-pad reset is bench-only on most Canon units, the service utility you need is not in the public Canon support download.

Will the same procedure work on every Canon model with this symptom?

The decision tree is the same. The specific menu paths and button combinations differ by model and firmware generation. Always cross-check the diagnostic-page sequence against the Canon user manual for your exact model number; using the wrong button combo can put the unit into a service mode you don't want to be in.

Is it safe to apply during a live print queue?

No. Cancel all queued jobs from the Canon embedded web server or the host print queue first. Power-cycle. Then run the diagnostic. Trying to clear a fault on a unit that's still chewing through a stuck job will give you misleading symptoms and possibly corrupt the spool.

Does this affect my Canon warranty?

Cleaning, firmware updates, and cartridge swaps under the user manual do not void warranty. Opening sealed compartments (head assembly, mainboard, PSU) typically does. Counter resets via the service utility are a grey area: they don't void warranty if the unit is in spec, but if you reset a waste-pad counter on a saturated pad, the eventual leak is on you.

Should I update firmware first or last?

Update firmware first if the Canon release notes for your model specifically mention your symptom. Otherwise, finish the cheap-fix path first, then update. That way if the firmware update introduces a regression, you can isolate it from the original fault.

What if I'm in a city without an Canon authorised service centre?

Canon has ASCs in all metros (Bengaluru, Chennai, Mumbai, Delhi-NCR, Hyderabad, Kolkata, Pune, Ahmedabad) and most tier-2 cities. For tier-3 / remote locations, the parts mailing route via Redington or direct Canon courier is usually 4-8 working days. The Canon mobile app has a service-request flow that schedules a courier pickup at no charge for in-warranty units.

Can I use third-party / refilled ink on the Canon unit?

Technically yes; pragmatically, weigh the savings against the head clog risk. Third-party ink saves around 60-70% per page but clogs the head about 2-3x faster on average, by my count. For low-volume home use it's usually fine; for a small office printing 50+ pages a day, genuine ink works out cheaper over the head's lifetime.
