Lexmark C935 Print Quality Troubleshooting


The Lexmark C935 printer is great machine designed with medium usage in mind. This machine can print up to 45 pages per minute for monochrome and about 40 pages per minute for color documents with excellent print quality.

Ricoh Printer Error Code SC541, SC542, SC543, SC544, SC545, SC546, How to Make It Disappear?


Error codes for printer models are meant to notify you for specific issues for your printer. However, these codes can sometimes be confusing and also need to be manually turned off when the issues have been resolved on your printer. The error codes SC541 to SC546 are generally associated with fuser unit’s temperature problem, thermistor, or BCU board. First always try to check and fix the printer parts. In most cases, the little temperature detector attached on the fuser needs to be replaced.



When the physical issue has been fixed, try to exit the error code by turning off and on the machine. However, sometimes it just not that easy when it comes to technical difficulties. In the case that simply turning off and on the printer does not work, here are a few steps to reset in the service mode:

1. Press the yellow button that says “Clear Modes”

2. Press the numbers 107

3. Press and hold the red button that says “Clear/Stop” until the screen changes

4. Select “Copy SP”

5. Select SP-5XXX that shows “Mode”

6. Keep pressing “Page Down” till the “5810 SC Code Ret” selection shows up. Select “5810”

7. On the right, press “Execute”

8. Press “Exit”

9. Press “Exit” two more times on the top right corner till the screen goes back to the initial error code display

10. Turn off the printer and wait for few seconds before turning it back on

The error code should be gone after the printer restarts.
