Ricoh Service Manual discussion tour

[PA3040]

Dear All,

I would like to start a discussion about RICOH color machine service Manual in details, So I would like to start first one of Metis series ( MP C 2003SP).

Your input of knowledge and experience in this regard is highly appreciated
First I would like to start from SP mode SP2-005 to 2-473 (Drum)

2005
[Charge DC Voltage: Fixed]
DC fixed voltage when Process control is off.


001 Standard Speed: K *ENG [0 to 2000 / 1350 / 10-V/step]
002 Standard Speed: C *ENG
003 Standard Speed: M *ENG [0 to 2000 / 1350 / 10-V/step]
004 Standard Speed: Y *ENG
005 Middle Speed: K *ENG [0 to 2000 / 1350 / 10-V/step]
006 Middle Speed: C *ENG
007 Middle Speed: M *ENG [0 to 2000 / 1350 / 10-V/step]
008 Middle Speed: Y *ENG
009 Low Speed: K *ENG [0 to 2000 / 1350 / 10-V/step]
010 Low Speed: C *ENG
011 Low Speed: M *ENG [0 to 2000 / 1350 / 10-V/step]
012 Low Speed: Y *ENG

Please explain your experience pints when you are changing of above values.
What is the operation of this mode?
What are the key factors that we need to take in to account at changing this values
What are the results that we can achieve,changing of above values
What are the speed mention above?

Thanks in advance

These values are used to manually control the DC charge voltages when Process Control is turned off.

Dear slim,
thanks for the reply

Is it possible to stop process control and how?

I invite to other members to contribute this tour

• It's not a good idea to disable process control.
• No need to change such SPs unless instructed to by an Ricoh technical bulletin or part of a adjustment procedure.

My 2 cent.

SP 3041 used to be used to turn portions Process Control On/Off. SP 3041-001 selected whether Process Control or the manual settings would control charge and bias voltages. Sp 3041 is not shown in the Service Manual for the 03's. I have used it in the past to be able to lower the development bias to handle some minor image problems that process could not fix. One instance was a customer printing a newsletter for a hunting group. A picture on a page had a hunter on a hillside wearing a bright red hunting cap. The cap on the page was a little less than 2mm in diameter. The problem was that it was such an intense color spot that the cleaning blade could not fully remove it and it offset down the rest of the page, getting slightly fainter each time. By lowering the development DC bias voltage 50 volts, I was able to eliminate the offsetting. I have since been given the attached document by a regional rep that works by lowering the toner concentration in the developer and raising the transfer current to maintain the the same image density.

Dear Slim and Cipher

Thanks for your gate ideas.

I would like to have more ideas before we move to next SP value.
