1035,2045 PCU's

[banginbishop]

Is there any right way of doing these crap units without pulling them out multiple times to stop them dirtying up. Oh and I vac out the old toner from the unit before putting it back in so its as clean as a whistle but I still get crap copies.

I've just ordered a complete PCU unit as it wont stop marking the drum and the customers not happy as i fitted an overdue service kit and now there having to pay for a whole new drum unit...

Well you vac the drum out, but i would put a peice of paper between the dev unit and drum when dev initializing, also replace the foam seals regualrly on the dev unit and pcu area, also remember to use the spring at the back of 2045's that hold cleaning blade 2 in place, clean mag roller on dev replacements and run about 5 skyshots before doing the td setup (2801). One more thing is to bend the charge roller contacts slightly so that they put a bit more pressure onto the drum, hope this helps.

If you aren't doing so already, ditch the 2nd cleaning blade. And just to verify, you are vacuuming out the coil on the top (under the handle) as well as under the main blade.

When I change, for example, the charge roller, I always replace the charge roller cleaner, and the cleaning blades as a set.

Did you do the adjustments after drum / charge roller replacement?

ID Sensor Adjustment (SP3-001-002)
Process Control (SP2-805)
Charge Roller Voltage Adjustment (SP2-001-001)

I started to regap the doctor blades on the DV units to .3mm a few months ago and my calls have dropped a lot as far as dirty copies and lines from charge roller.
A couple of machines went PM to PM without a call after I did this.
Its worth a try.

Right first up thanks for the replies on my thread



M/c is set up per manual with id, td and charge roller etc.





oh and i'm forever changing the seals as customers keep removing the pcu and ripping the dev and drum seals to remove jams

strange - I almost never got these kind of troubles after refitting the PCU's

During PM I change the Drum, Blade, Charge Roller and Cleaning Roller "as a set" and vac out just the PCU area I can reach without disassembling more parts of it. We're working with PM kits mostly.

Ricoh does "officially" recommend not to use the 2nd blade for the A2045 and newer machines since a few month.

If I get dirty copies after drum replacement, I just make 10 to 20 copies and then they'll be clean.

Not had a lot of problems with the Savin 2045/4035 models. But the 8035 have crap mag rollers.

How are you adjusting the gap on the doctor roller? never done it, don't now how.

Seen this posted somewhere? I'd love to remove them cause they build up particulate.

Here it is (for the MP5000):

Technical Bulletin PAGE: 1/1
Model: Alex-C1 Date: 10-Nov-08 No.: RD009032

SYMPTOM
Vertical white lines
CAUSE
Foreign material sometime gets stuck in between the OPC and 2nd cleaning blade, which scratches the surface of the OPC.
SOLUTION
Production line:
The 2nd cleaning blade was deleted from the PCU.
Machines in the field:
For both newly-installed machines and machines already in the field, remove the 2nd cleaning blade (P/N: AD041105) at the next PM visit for the 2nd cleaning blade.
Note: When the 2nd cleaning blade is removed, the following parts must also be removed.
- Snap Ring (P/N: G0652681)
- Bushing (P/N: 52031852)
- Spring (P/N: AA062258)

Couldn't found another tip like this for the A2045 series but I see no reason why we shouldn't handle it the same way with all "2nd blade" machines.

Jan is that an official invite to send you my nasty PCU's for you to rebuild - job done and sorted thanks Jan

You don't want to use these units AFTER shipping^^

Also, if you have a MFP in the given family and it's just puking toner for no reason.... change the HVSP.... See what happens

[SGT_Snacks-64]

Nope.... can't ever say I've had this problem in the past. I usually fit the Drum, Cleaning Blade and Charge roller, vacing the innards and the cleaning brush roller. Remove the second cleaning blade.

I know when I was a complete n00b to all this I bent the Charge terminal on the PCU doing a change like this, causing black copies. But no problems with PCU replacement! Maybe I'm just lucky.

I actually don't mind the range (Well, apart from the c4.5 and Alex anyway!)
