Problem

843.xx; ADF elevator tray motor time-out error service check; Problem scanning from ADF; Copying issue; scuReadProc:3141; Autocomp; ADF tray immediately lowers

Solution

What you will see
 

The following scenario occurs when trying to copy from the Auto Document Feeder (ADF):

  • The ADF tray immediately lowers.
  • The printer posts 843.18 scanner error (see screenshot below; note: click it to enlarge).
  • Device then reboots and disables scanner.
  • The error appears only when using the ADF. The machine copies from the flatbed with no problem.

843.18 scanner error appears before the printer reboots and disables the scanner.

NOTE: The issue most likely started after replacing ADF maintenance kit.

 

Troubleshooting
 

Before calling for service, check whether the ADF Autocomp is installed and fully seated. See procedure below:
