    CANON C1 - BLANK COPY

    Some suggestions please - got in this morning and my C1 fired up just fine - then went to print and got blank sheets - I put an original on the glass and same thing - went to the test charts from the service mode - same thing - took a few minutes to pull and reseat the charge and pre-transfer and still no change - no other error codes just blank copy - no time to further explore today will deal with it as a happy monday project.

    thanks

      Print some blank pages to get an error.Check if you have image on the drum ore ITB belt.Probably you did not forget something to connect ore some screw?I'm very curious.Good luck.
      If it ain't broke, don't fix it

              Thanks for the suggestions -
              we switched to the backup machine and I pursued this further yesterday-
              1) no image on the drum, switched the charge and transfer from the back up machine still no image - reseated all connectors for the processor unit (again) to be sure a canon connector issue wasn't getting me - finally ran 25 copies and got a 000020-0186 error - patch sensor issue - obviously if there is no image on the drum the patch sensor won't read a "no image" -

              2) went into service mode and checked the charge and transfer high voltage settings - they are where the service manual says is a start point from factory -

              3) Laser? Drum Bias? (yes there is toner in the machine - had a customer run out of toner on an old panasonic once)

              thanks

                  Check the black plastic cover and slide on the P-kit.
