Fix Lexmark 80.36 Maintenance Kit — reset not clearing, counter won’t reset, maintenance required message stuck

Technician

Hey! Let’s get your Lexmark 80.36 Maintenance kit alert to actually clear.
A couple of quick details so I can target the right procedure: which Lexmark model (MS/MX/CS/CX, MX710, MS812, etc.) are you using, did you install a genuine Lexmark maintenance kit (fuser, transfer, rollers) or third-party parts, and is the display saying “80.36 Maintenance kit out”, “80.36 scheduled maintenance”, or “maintenance required – replace maintenance kit” even after you’ve run a reset?

Customer

It’s a Lexmark MX series. We installed a maintenance kit with fuser and feed rollers. The printer still shows 80.36 Maintenance kit every time it powers on. We tried the reset option from the menu, but the warning won’t clear.

Technician

Got it — classic scenario.
The 80.36 Maintenance Kit code is a page count / life counter tied to your kit components. If the reset won’t clear, it’s usually one of three things:
1) The maintenance counter wasn’t reset from the correct Configuration / Maintenance / Reset Maintenance Count menu (varies by series).
2) The printer doesn’t “see” the new kit properly — e.g. fuser not fully latched, wrong kit FRU, or a door/thermistor/drive issue keeping the engine in a faulted state.
3) There’s NVRAM corruption or outdated firmware, so the 80.36 warning persists even though the hardware is new.
Let’s run a proper Lexmark-style verification: confirm the kit, run the right reset, then only if necessary touch advanced NVRAM options.

Customer

We used a third-party maintenance kit listed as compatible. We just went into the regular menu and hit something like “Reset maintenance”. Maybe we’re missing the right place?

Technician

Step 1 — Use the correct Lexmark maintenance counter reset
On most Lexmark MS/MX devices:
1) On the control panel, tap Menu or Settings.
2) Navigate to Device → Maintenance → Maintenance kit (or Configuration Menu → Reset Maintenance Count).
3) Select “Reset maintenance kit” or “Reset maintenance count” and confirm.
4) Power the printer off and back on to verify if the 80.36 message disappears.
Important: some Lexmark engines only expose this option when the correct kit type is installed and all covers/sensors are closed. If you don’t see the reset entry, that’s a clue the device isn’t fully satisfied with the kit or sensors yet.

Customer

We did a reset like that, but 80.36 is still there after reboot. Could the non-Lexmark kit cause the reset not to stick?

Technician

Very possible.
Step 2 — Confirm the maintenance kit & sensors
• Make sure the kit matches the exact Lexmark part number for your model (many 80.xx codes are model-specific). A mismatched fuser or transfer roller can trigger life warnings or keep counts from resetting cleanly.
• Power off, reseat the fuser assembly, check side latches, and ensure no bent pins or broken plastic. A loose fuser or open rear door can make the controller think the kit was never really replaced.
• Inspect key paper path sensors and pick rollers included in the kit. If a worn sensor flag or roller wasn’t changed, the printer may hit thresholds again quickly, making it look like the 80.36 maintenance kit reset won’t clear.
Third-party kits can work, but if tolerances are off, you sometimes need an expert to verify mechanical fit and life thresholds.

Customer

If hardware’s fine and it’s still stuck, how do we check for NVRAM or firmware issues safely? I don’t want to wipe network settings by accident.

Technician

Step 3 — Use advanced resets only when needed
Some Lexmark models store the maintenance count in NVRAM and expose extra options in a configuration/diagnostic menu. General safe rules:
• First, update to the latest recommended Lexmark firmware for your model — this alone can correct stuck maintenance counters in certain revisions.
• Only if the standard menu reset fails should you consider a targeted NVRAM maintenance reset or “Clear maintenance count” from the diagnostic screen.
• Avoid full NVRAM or factory resets unless guided — that can wipe network, email, authentication, and tray config, which is painful in production.
If you’d like, an expert can step through which hidden menu is appropriate for your specific Lexmark so we clear 80.36 without blowing away important settings.

Customer

We run a fleet. Some units show “80.36 Maintenance kit out soon”, others “80.36 out / required” even after kits. How do we standardize so the reset works across all Lexmarks?

Technician

Step 4 — Fleet standards to avoid recurring 80.36 issues
For multiple MS/MX/CS/CX devices:
• Use documented, model-specific Lexmark maintenance kits and track page counts so replacements happen near schedule, not far overdue.
• Train techs to run the reset from the correct path immediately after installing the kit on each printer.
• Keep firmware aligned across the fleet; mixed firmware levels can behave differently with the same 80.36 Maintenance Kit thresholds.
• Document whether you accept third-party maintenance kits. If you do, test one device first to ensure the reset and sensors behave before deploying to all units.
Following this reduces “reset won’t clear” calls and keeps your Lexmark maintenance alerts meaningful instead of noise.

Customer

Is there any risk in running with 80.36 active if print quality seems fine? We’re tempted to ignore it.

Technician

Understandable, but there are trade-offs.
Leaving 80.36 Maintenance kit uncleared means the printer believes the fuser/rollers are overdue. This can lead to:
• Increased risk of jams, ghosting, background, and poor fusing as you exceed the designed duty cycle.
• Users ignoring other warnings because the panel “is always complaining”.
• In some firmware, additional service codes once counters go far beyond limits.
Best practice: if the kit is truly replaced, fix the reset. If it isn’t replaced, use the warning as a prompt to do proper preventive maintenance instead of just clearing it.

Customer

So if the right kit is in, reset done correctly, and firmware updated, but 80.36 stays, what’s left to check before service?

Technician

Step 5 — Final checks for a stubborn Lexmark 80.36
• Confirm the device is not also throwing related fuser/engine errors (over-temp, under-temp, paper feed faults). Those can block a clean maintenance state.
• Double-check the maintenance kit life in the reports menu. If the value never changes, we may be looking at a controller or NVRAM fault.
• Inspect for aftermarket parts missing required flags/gears that indicate “new kit” status on some models.
At that point, it’s worth having a Lexmark-experienced tech review logs and engine settings rather than guessing. That’s exactly what we do in live chat sessions.

Customer

Thanks, that helps. So most 80.36 reset issues are either wrong reset path, wrong kit, or firmware/NVRAM quirks?

Technician

Exactly. To fix a Lexmark 80.36 Maintenance Kit reset that won’t clear you generally need to:
• Confirm the correct, fully seated maintenance kit (fuser, rollers, transfer parts).
• Run the official maintenance count reset from the proper menu, then power cycle.
• Update firmware and avoid unnecessary full NVRAM wipes.
• For fleets, standardize parts and procedures so the code behaves consistently.
Do that, and the 80.36 warning should stay gone until the next real cycle. If you’d like help mapping this to your exact Lexmark model, open the chat and we’ll walk you through it step by step.

Quick answer: the accepted fix

Accepted fix when a Lexmark 80.36 Maintenance Kit warning won’t clear: install the correct kit, reseat the fuser and rollers, run the official “Reset maintenance kit / Reset maintenance count” from the device menu, update firmware, and avoid full NVRAM resets unless guided. If 80.36 persists, check sensors, kit compatibility, and controller health — or chat with an expert for a model-specific walkthrough.

FAQ

Step-by-step: clear Lexmark 80.36 Maintenance Kit correctly

1. Install the correct maintenance kit for your Lexmark model, including fuser and rollers; ensure all latches and doors are fully closed.
2. From the control panel, open the Settings/Configuration menu and navigate to the Maintenance or Configuration section.
3. Select “Maintenance kit” or “Reset maintenance count” and confirm the reset.
4. Power the printer off and back on; verify that the 80.36 Maintenance Kit message no longer appears.
5. If the code persists, update firmware, re-check kit compatibility and seating, and only then consider a guided NVRAM or service-level reset.

Note for managed & mixed environments

1. Document the exact reset path for each Lexmark series used in your organization so on-site staff follow the right steps.
2. Keep a record of kit part numbers and page counts per device to align maintenance windows and avoid premature or missed resets.
