Got a MX5141 roughly 200K poping an E7-11 every time you go into copy mode or scan mode. We have replaced the SCN PWB and LED PWB on the scan unit. Still nothing. Both the DSPF lamp lights up and the mirror lamps light up.
In test command 63-2 OC shading test fine, DSPF shading errors out.
You can remove the DSPF and go flattop and it still pops the E7-11
Reference sheets look just fine no visible markings
The unit still prints and receives faxes just fine.
Any ideas would help a ton
