P-14 means there is a skew problem. My experience is that it mostly deals with the black IU. 1st pull out the black IU and reseat it. But before locking the black IU hold it in place with your hand then lock it. Sometimes it doesn't sit right. The other alternative is if it doesn't work try replacing the black IU.

PS - as a precaution reseat all IU's

Hope this helps!

Thanks 8050. I replaced the black I/U already and have reseated all I/U's as well. I looked on Minolta's SSD site for the P14. Nothing there except what you said...replace the I/U.

There is a special firmware from KM for this problem. PRCB is the only part that has to be flashed with this special firmware (GC1-22).

had this issue a few weeks ago, tried I/U replacement, no help, installed special f/w, no help. Test mode charts showed black leading in one direction, lagging in other direction. Wound up replacing the PH to resolve this. I am assuming the poster ment 451C. EMujo

Don't waste your money and time on replacing the ph units. Follow this procedure step by step and I guarantee you the P-14 will go away, I've done this on atleast 30 machines and have had success with each one.

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 has been a fix for me 100% of the time with P-14 codes.

For reference look at TAD # TAUS0703835EN08 in the KM Knowledgebase.

this issue could be firmware depending on the firmware you have at the moment also could be transfer belt check with KM before wasting money.

My Fix was shifting C and M laser to value 300 manualy.

Then all the other adjustments stabiliser reset and full gradation adjust.



"Quite a mile away from initial settings but it worked for me."

We have to replace the black IU to solve the problem.
Bad black IU unit also show up same problem in different machine.

Nice one.

I have changed Bk IU and ITB and no difference. Cleaning skew mechanism apparently helps as someone already mentioned here already...I did not need to do that...my fix was new values in Skew.

Thanks for the info on how you have fixed it!

Just Flashed one of our machines with GSR-R6 and we shall see, if the P-14 comes back. I had it on Manual Skew Adjust with figures

C-480
M-480
Y-193

Now with the Firmware I did:

Skew Adjust Reset + Initialize and Image Stabilise

Flashed with GSR-R6

Skew Adjust Reset + Initialize and Image Stabilise

P-14 went away

Magic :) will see for how long :)

Thanks for watching:) Have a nice weekend folks.

Hi.

Thank you very much.

The GSR-R6 isn't the magic firmware to look for.

ALL the Gxx-R6 firmware support the P-14 fix (Threshold changed)

On older firmware (J8/R5 etc )
If the skew correction cannot be done ...then the skew control motors go back to home position.

ON R6 firmware the skew control stays at maximum adjustment if outside the range.

from notes
5. When the alert code P-14 is detected after PH and IU are changed, color registration error or skewed image may occur because the skew correction control is not performed.
