C253 ADF jam 6602

[habik]

Whether single or multi page it jams passed reading section and throws 6602.

Tried 3 different ADFs Firmware re-flashed , system error clear , data clear, replaced scanner relay boards. Nothing helped so far


Going to try NVRAM and then PRCB Engine board.

Just wanted to know if anyone had anything similar.

Cheers

Just to add..when there is NO document in the ADF it still tries to lift and feed as if there is one. This has been done after NV RAM clear, shame I haven't noticed it before NV RAM clear ..I love this series..so much fun for Friday afternoon

It happens even when ADF is lifted off with 2 different ADF's
