Lexmark’s business printers handle real office volume well, but two issues generate most service calls: recurring paper jams and vertical streaking. Both usually trace back to a specific, fixable cause rather than a failing machine.
Lexmark printers are a common choice for offices needing reliable, higher-volume printing, and most of what generates a service call falls into one of two categories: the printer keeps jamming, or output has developed vertical streaks. Neither is usually a sign the printer is failing — both have specific, checkable causes.
Vertical streaking: why it's usually not the cartridge
The instinct when print quality degrades is to replace the toner cartridge, but persistent vertical streaks are more often caused by a dirty or worn transfer roller, which physically transfers toner onto the page. A contaminated roller leaves a consistent streak at the same position on every page. Cleaning it (following the specific process for your model) resolves this far more often than a cartridge swap does.
Recurring paper jams: what to actually check
| Likely cause | What to check |
|---|---|
| Paper quality or condition | Humidity-affected or low-quality paper jams more often — try a fresh ream from a sealed package |
| Overfilled paper tray | Paper loaded above the fill line can cause misfeeds — check the tray’s marked maximum |
| Worn feed rollers | Rollers lose grip over time and high page counts — a common cause on older or high-volume units |
| Torn paper fragments left behind | After clearing a jam, small torn pieces can remain and cause the next one — inspect the full paper path carefully |
| Incorrect paper size/type setting | A mismatch between the tray setting and actual loaded paper causes feed errors |
Check the full paper path after every jam, not just the visiblespot
It’s common to clear the visible jam and assume the problem is solved, while a small torn corner remains further along the paper path — causing the “same” jam to recur almost immediately. A full inspection after clearing takes an extra minute and prevents a repeat call.
Step-by-step: cleaning the transfer roller
- Power off and unplug the printer: Safety first — the roller area involves internal components that shouldn’t be accessed while powered.
- Locate the transfer roller per your model’s manual: Location varies by model — check Lexmark’s documentation for your specific printer rather than guessing.
- Clean gently with a lint-free cloth: Avoid liquid cleaners unless specifically recommended for your model — dry or lightly damp cleaning is usually sufficient.
- Reassemble and print a test page: Compare against the streaking you saw before — if it’s resolved, you’re done; if not, it may be a worn roller needing replacement.
When to call for service instead
- Streaking persists after cleaning the transfer roller.
- Jams recur multiple times daily despite checking the full paper path.
- Feed rollers show visible wear or damage.
- The printer displays a hardware error code that doesn’t clear.
Frequently Asked Questions
A consistent streak at the same horizontal position on every page points to the roller. Random or inconsistent streaking is more likely toner-related. When in doubt, try cleaning the roller first since it’s the more common cause.
Yes, more than people expect — lower-quality or humidity-exposed paper jams noticeably more often. If jams are frequent, switching to a fresh ream of quality paper is a cheap first test.
This depends heavily on print volume rather than time elapsed — high-volume offices may need replacement more often than the calendar alone would suggest. If jams increase gradually over time despite good paper and clean paths, worn rollers are a likely cause.
Conclusion
Between checking the paper path thoroughly and knowing to clean the transfer roller before replacing toner, most Lexmark service calls are either avoidable or resolvable without a technician — worth trying both before assuming the machine needs professional attention.
