    [Error Code] P14 on Konica C451

    Hey all, please help before I go insane. Got this C451 with P14 error that wont go away. Updated firmware, Replaced transfer belt, IU units, IDC reg sensors, Laser unit - PH relay board and even PRCB control board. Copy quality is great and machine works well - if only that alert would go away..
    Hey what ya doing? - just screwing around.

          You haven't mentioned if you've done the Image Stabilization and background resets after PH and or IU replacement. Emujo
          If you don't see your question answered in the forum, please don't think it's OK to PM me for a personal reply...I do not give out firmware and/or manuals.

              There is a special firmware for this P14 problem to give a wider window of detection. Not got details to hand tho.
              Please do not PM me without asking first.

                  Have you performed the PH skew adjustment?

                      P-14 means there is a skew problem. There is a special firmware for this problem. PRCB is the only part that has to be flashed with this special firmware. So follow this step by step----1. Do "Skew Adjustment Reset" then run "Initialize+Image Stabilization"
                      2. Turn off copier.
                      3. Apply firmware GC1-22 for the Printer control. MFP firmware must be at atleast R5.
                      4 Do "Skew Adjustment Reset" then run "Initialize+Image Stabilization" again.
                      5. Turn off and on the copier.
                      6. Run Gradation for all three modes and then run Stabilizer again.

                      This procedure usually fixes P-14 codes.

                              Hello,

                              We're also having this problem on a machine but we can't find the Special FW. Can you please provide that firmware?

                              Thanks

                                  It's not special firmware. It's under base firmware.
