How to reset Canon PIXMA waste ink counter on Pantum

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

Why I wrote this one

I run a small print-shop service on the side - mostly weekends, sometimes after-hours when an SMB or a home user calls in panicking. Last month at an ESS Bengaluru reseller demo bay (off Hosur Road), a customer had picked up a Pantum unit and could not get past the basics. They wanted exactly this: Clear the waste-ink absorber counter on a Canon PIXMA unit. The shop walked them through a generic setup, the unit threw a AADSTS50076 hint banner on the panel, and the customer ended up at my desk with the box still in plastic.

This guide is the same runbook I used that evening. It is the Waste Ink Counter Reset flow specifically in a Pantum context, but I have added the cross-checks you need when the unit is part of a heterogeneous fleet - because in real Indian SMB offices, you rarely have one brand of printer. There is a Brother MFC in admin, a HP DeskJet in accounts, a Canon PIXMA in design, and someone's personal Epson EcoTank on a side desk. Getting one task right per brand sounds simple until you realise each brand hides the menu in a different place.

One brand quirk to put on your radar right away: Pantum BM5100ADW factory reset is not exposed on the panel - you have to use the CW1000 web UI at the printer's IP (default admin/000000). I learned that one the hard way and the customer was patient enough to let me re-do the setup the next morning. Saves time if you know it going in. The tool I keep on the laptop bag for work like this is PRTG Network Monitor 24.2.93 (SNMP polling) - reliable, and it covers most of the customer requests I see week after week.

What you need on the desk before you start

Print-shop work is mostly preparation. Once you start, you do not want to be running back to the laptop for a missing tool or hunting for the toner cartridge box for the model number. Get all this within arm's reach before you start.

Tools I usually have open

Even if you only end up using two of these, the others are useful when something goes wrong. Wireshark in particular is the one I reach for when the unit advertises a service but a client cannot find it - and yes, that happens with scan-to-email and SharePoint connectors on switched networks more often than you would think.

The actual procedure - step by step

This is the path I used in the a print shop on Chickpet main road, Bengaluru job last month. It is written for a Pantum unit with current 2025-2026 firmware. Older revisions may shuffle the menu structure; the labels are stable across firmware generations but the menu depth changes.

  1. Power the unit on and let it finish its boot self-test. On a Pantum cold-boot, this takes 90-150 seconds. Do not interrupt - on Brother MFCs I have seen interrupted boots leave the unit asking for cartridge re-seat on next power-up. Wait for the home screen.
  2. Confirm network connectivity. Print a network-config page. On Brother, hold the Wi-Fi button for 3 seconds then tap 'Print'. On Canon PIXMA, hold Resume for 2 seconds. On HP, Menu -> Reports -> Network Configuration. On Lexmark, Menu -> Reports -> Network Setup Page. The IP address is what you need.
  3. From the admin laptop, open the printer's web UI at https://<printer-ip>. If the cert is self-signed, accept the warning. Sign in as admin. Default credentials are: Brother (admin / initpass), HP (admin / blank on first boot), Canon (ADMIN / canon), Lexmark (admin / admin), Kyocera (Admin / Admin), Ricoh (admin / blank), Xerox (admin / 1111). Change the default immediately - I have seen GeM compliance auditors flag default-password MFPs as a sev-2 finding.
  4. Navigate to Service Mode -> EEPROM clear -> Absorber Counter Reset. On the Pantum web UI this is the canonical path. If your firmware revision shows a slightly different label, search for the keyword in the menu (most Pantum EWS revisions have a search box at the top).
  5. Fill in the operation-specific fields. For Waste Ink Counter Reset, the required fields are listed in the section below.
  6. Save and apply. Pantum firmware behaviour: HP and Canon auto-apply on Save; Brother, Lexmark, Kyocera require an explicit 'Submit' or 'Apply' click after Save; Xerox and Ricoh require you to acknowledge a warning prompt that says configuration will reload. The reload takes 30-90 seconds, during which the device is offline.
  7. Test from a real client. Do not trust the web UI confirmation. Run the operation end-to-end from a normal user laptop on the same network you will use in production. If the test fails but the web UI says success, the issue is almost always firewall / network ACL on the client side.
  8. Document and log. Snap a photo of the final config, save it to a folder labelled with the customer name, the Pantum serial, and date. Customers call back six months later with 'it stopped working' and your photo is the baseline to compare against.

Two Pantum quirks worth calling out before you push the config live: Pantum BM5100ADW factory reset is not exposed on the panel - you have to use the CW1000 web UI at the printer's IP (default admin/000000) Also worth knowing: Pantum scan-to-email uses port 587 only with the legacy SSL cipher list; modern Gmail SMTP rejects the handshake unless you firmware-update to 1.7.31 or newer.

What the waste ink counter actually tracks

The waste-ink counter is a firmware counter that estimates how much ink has been pumped through the head-cleaning cycle into the absorber sponge at the bottom of the chassis. Cleaning cycles, nozzle checks, and power-on priming all add to it. When the counter hits ~95%, the panel throws 5B00 (Canon) or 0xc4eb827f (Epson) or E-08 (Brother) and the unit refuses to print.

One Pantum note worth bookmarking: third-party WIC reset tools (WIC Reset Utility 1.18 is the most common) work but are not endorsed. They write a one-shot reset code that costs USD 9-12 per reset. Free service-mode key combos are documented in unofficial forums and work on most older models. For mission-critical units, replace the pad and use the OEM tool.

Verifying it works - real commands

# Canon PIXMA G-series service mode entry (manual key combo):
# 1. With unit OFF, press and HOLD the Stop button.
# 2. While holding Stop, press and HOLD Power.
# 3. Release Stop, keeping Power held.
# 4. With Power still held, press Stop 5 times.
# 5. Release Power. Panel shows '0' = service mode active.

# Then send the counter-reset command:
# Press Stop 4 times (Absorber Counter Setting), then Power to apply.
# Press Stop once more to display, Power to write back to EEPROM.

# Verify by printing the EEPROM dump:
# Service mode -> Stop x2 (Print Test) -> Power
# Look for 'D=000.0' under Ink Absorber - that means counter reset.

# Epson WIC verification on Windows:
# Run 'WIC Reset Utility' -> Read Waste Counters
# Both Main and Platen pad counters should show under 30%.

When it fails - the real root causes

When the procedure does not work, the cause is almost always one of these five. I rank them in the order I check on a real service call.

  1. Firmware out of date. Pantum pushes minor revisions every 4-8 weeks. Anything older than 6 months has a non-trivial chance of menu paths having shifted or a known bug applying. Update first, retry second.
  2. Network reach failure. mDNS blocked, VLAN mismatch, SMB share unreachable, SMTP port blocked. Run a ping and a port-test from the admin laptop before blaming the printer.
  3. Credential mismatch. The admin password the customer thinks is set is not what is actually set. Try the default, then the customer's usual pattern, then ask for a reset.
  4. Hardware-feature mismatch. The model SKU does not include the feature the customer thinks they bought. Worth verifying against the spec sheet before spending an hour debugging an option that does not physically exist.
  5. Genuine hardware fault. The unit throws a panel code like 1700 that maps to a real service condition. At that point, the configuration step will not fix it; the unit needs service or RMA.

Out of every 10 service calls, my rough split is 4-3-1-1-1 in that order. Most problems are firmware or network. Hardware faults are the rarest cause, even though customers blame hardware first.

Realistic cost picture (Indian SMB, 2026)

Customers ask for prices in the same call as the configuration help. These are typical 2026 channel quotes I see in Bengaluru and Chennai.

Channel-wise, I usually source from Compuage Infocom (cross-brand printer + ink-tank dealer) for warranty-sensitive deployments, and from Amazon Business / Flipkart Wholesale for sub-INR 30,000 SKUs where GST invoicing is the priority. GeM AMC for an SMB MFP runs INR 2,800-4,500 per year (USD 33-54) including two preventive visits and labour; toner is consumable, billed separately.

Important rule on consumables: a 30% saving on a non-OEM toner can cost you INR 18,000 (USD 215) when the drum fails six months later because the cheap toner left residue. I never recommend non-OEM consumables for production MFPs. For occasional-use home printers, the calculus is different.

One field story I still think about

About eight months ago I got a call from an export house front office in Tirupur. They had three Pantum units on the floor and one had started refusing to scan. The panel was clean, no obvious error, just a 'communication error' banner that came and went. The owner had already reset it twice. He was about to call the service centre, which on a Saturday in Bengaluru means a Monday visit at best.

I drove over with the toolkit. Pulled out Ricoh Device Manager NX Lite 1.7 and started capturing traffic from the printer to the laptop. The SMTP authentication was actually succeeding - the printer was getting an OK back from Office 365 - but the unit was throwing C7990 in its internal log buffer about 12 seconds after the auth success. Strange.

The fix took twenty more minutes to find. The unit was set to TLS 1.0 fallback, and Office 365 had quietly stopped accepting TLS 1.0 sessions four months earlier. The auth was succeeding because the cipher negotiated to TLS 1.2 for the first handshake; then the printer was attempting a TLS-renegotiation for the data phase and falling back to 1.0, which the server then dropped. The fix was three clicks: web UI, Security, Encryption, set 'Minimum TLS version' to 1.2.

What I took away from that call: in 2026, every SMB MFP needs at minimum TLS 1.2 for outbound, and most of the silent communication errors I see are TLS-version mismatches at the email or scan-to-cloud edge. The firmware default on units sold in 2022-2023 still leans on TLS 1.0; you have to bump it up after install. I now include that step in every onboarding checklist.

Total time on site: 65 minutes. Customer paid INR 1,000 (USD 12). The unit has been stable since. The other two units got the same fix preemptively that afternoon.

FAQs I get from actual customers

Will this work on the international variant of my Pantum unit?

Mostly. The web UI and the menu paths are stable across regions; what differs is the cartridge region-lock and a few feature toggles (some markets get features others do not). For configuration like scan-to-cloud and waste-ink reset, the path is identical. For date/time on fax-capable units, the path is identical but the default time zone differs by region.

How often should I run preventive checks?

For SMB units printing under 1,000 pages a month, every 3-4 months is fine. For production print shops doing 10,000+ pages, monthly: check the maintenance counter, the fuser life percentage on lasers, the ink-pad fullness on inkjets, and the firmware revision.

Will this void my warranty?

Standard configuration through the official web UI or panel menus does not void warranty. Waste-ink counter reset using the official service mode is technically a service operation; OEM service centres will reset it for free under warranty if you take it in. Third-party WIC reset tools work but Canon / Epson can detect the tampering on the next service inspection.

What if my model is a slightly different revision?

Cross-check the model code on the rating plate at the back of the unit. Major firmware generations sometimes shift menus by one or two levels. Search for the keyword inside the EWS - most modern Pantum web UIs have a search box that finds menu options.

Can I roll back if something goes wrong?

Configuration rollback: yes. Most Pantum EWS let you export the current config to a .bin or .json file before changing anything; you can re-import it to roll back. Firmware rollback: no on most units - newer firmware writes version-locked bootloader entries that refuse older binaries. Take the config export before you make changes.

Is the customer's data safe during this procedure?

For scan-to-cloud and SMTP setup - yes, no user data is touched. For waste-ink counter reset - yes, no data is wiped, only the counter EEPROM cell. For factory date/time on fax units - the fax journal may roll back to zero on some Brother revisions, so export the journal first.

Should I update firmware before or after this procedure?

Before. Always before. Firmware updates can shift menu paths and can include fixes that make the procedure go smoother. The exception: if the customer is mid-deadline and a firmware update is non-trivial (30-45 minutes including reboot), defer to after.

Keeping the unit healthy so this is the last time

After the immediate fix, these habits keep the Pantum unit healthy.

None of this is glamorous. All of it pays back in fewer Saturday-evening emergency calls.

Closing the loop

The Waste Ink Counter Reset flow in a Pantum context is not complicated once you know the menu path and the gotchas. The first time takes 30-45 minutes because you are looking around the EWS for the right menu. By the third time it is under 10 minutes including the verification test.

If the procedure does not work after one careful pass, do not keep retrying in panic mode. Take a screenshot, take a panel photo, save the network-config page, and step back. Most failures are network or firmware related, and both are diagnosable from the artefacts you just captured. Repeating the same wrong steps faster does not fix anything.

I keep a small printed cheat-sheet in the toolkit with the default credentials for every major brand and the panel-reset shortcut for each. It lives next to the toner-vacuum and the spare network cable. Boring, but it has saved me twenty minutes of fumbling more times than I can count.
