SC285 Pro C5100

[BsK]

Hi,

I've got a Pro C5100 coming up with SC285 and SC496 (both Music errors). These errors occur when you run SP-3011-4 (Full music) however if you run force pro con , 3011-01, it passes with all 1's when you check 3012.

The ID sensors array has been replaced, the ITB is in good condition as are the PCU's. The CQ is good and colour registration is in. The Encoder sensor on the ITB ass'y has been cleaned and the PTR has been replaced too.

Any help would be appreciated.

Goose's Guide has a hit for SC285/SC496. Says that the Tech. replaced entire ITB unit to resolve.
Another hit says ID/MUSIC sensor replaced, but you've done that.

i would to try to clean or replace the potential sensors !

but here is the steps for these errors from Ricoh service manual


* The results of MUSIC pattern reading failed 4 times while the machine is
turned ON.
Details:
• When MUSIC fails 4 times while the machine is turned ON. (The
count is cleared when the machine is turned OFF e.g. when entering
sleep mode.)
• TM sensor sampling error
• Sensor LED adjustment error
• Patch number error
• Transfer belt flaw error
• Main registration error
• Sub registration error
• Main scan magnification ratio error
• Main scan magnification ratio deviation error
• Belt flawed or smudged
• Sensor smudged or defective
• Pattern density defection
• Cycle the machine off/on.
• Replace the TM sensor.
• Replace the belt.
• Process control
• Cleaning

Has the problem been solved? If so, how?

Thank you.

How many prints has the transfer belt and bias rollers got on them? They usually need replacing around 1.5m.

Had that same problem and it went away on its own. Details here.

Not sure if this will help you but i once had a C5100 machine that would not run the color registration in user tools it would fail. I had to go in service mode and zero out the laser mirror adjustment motors and then run the MUSIC process. the motors were at the maximum of the adjustment range and would not allow the registration process to complete.

There's a mention of that in the service manual, so I tried it too - didn't make a difference. But yes, I believe that if the values are too far away from standard will stop the engine from performing the adjustments. That's also one of the reasons why, when I find an adjustment trouble that I can't solve by traditional means, I backup the NVRAM and then try again after resetting the engine data (didn't work in this case).

Give it a full service and replace parts in that area over life not forgetting the ptr and wax bars etc with are in them areas

If you back up nvram and then clear nvram the details what you load back on from the backup would have the same information on it
