Epson AcuLaser C900 error 6021 - Epson AcuLaser C900 Printer

SOURCE: Epson Aculaser C900 - Paper Jam Notice, but no Jam?

Step1
Turn the printer off and on to see if it can automatically clear some or all of the jam. Many printers provide an error-code listing on the front panel display for the area where the jam occurred. If your printer shows an error code, be sure and check the printer manual to see if that identifies the area of the printer where the jam occurred. 
Step
2
Turn off the printer. 
Step
3
Remove any paper trays. Inspect them for wrinkled or damaged paper. 
Step
4
Open any other doors that give access to the printer's paper path and to the toner or ink cartridge. 
Step
5
If necessary, remove the toner or ink cartridge. Place it in a bag or away from light to avoid damaging it. 
Step
6
If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly (see A). The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam. 
Step
7
If the paper does tear, try rotating the roller gears manually to free the paper (see B). Don't force anything, though. 
Step
8
Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on. 
Step
9
If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.

Hi there

This suggests a fuser error. This is the hot unit at the rear top of the machine.

Steps are as follows:-

1. Open COVER FUSER.
2. Draw out the COVER RH boss from the hole on COVER FUSER while pushing
COVER RH outward, and remove COVER FUSER.

After removal check coninuity across heater lamp amd thermistor terminals. If either shows anyhing more than 13 Ohms then you need to replace your fuser unit.

Anything more than that requires hands on technical expertise.

Good luck

I have successfully cleaned an Epson Acculaser C1900 colour laser printer.

Is anyone interested in a totorial (with photos) on doing the job. Before I had white stipes going down the pages. With a screwdriver and vacuum cleaner, it's as good as new.
