Ricoh Mp 6001 - Printing light / faded black after reset...

[xXFlipPTXx]

Hi,
i had an issue on the machine ricoh 6001 that made me to reset all of it. Now it's printing light, kinda faded. I remember that this could be fixed with some options, because isn't the first time i have reset the machine , i've tried to forced toner suply few times but isn't black enough as i wish...
What other method should i do to dark more (use more black) the printings besides usind the force toner suply option?
Before the reset, it was printing well, black real black....
Remember this machine only use black toner.
Any help would be appreciated.

Thanks,
Flip

Probably a dirty ID sensor. Check SP 3001-001. If it is much more than 100 you have a dirty sensor which will make the ID patch look darker than it actually resulting in the 6001 under toning. Remove PCU, follow instructions in the service manual. Remove the drum and place it in a drum cloth. Clean all toner from the PCU frame. If you use a vacuum, do not vacuum close to the ID sensor as static will destroy the sensor. Use a camera lens brush to clean the sensor followed by a soft cotton cloth slightly dampened with water only.

After putting the PCU back in the 6001 and closing all doors, run SP 3001-002. This should change SP 3001-001 to between 50 and 80. Run SP 2962 to manually run ProCon.

Thanks, I could check that option, but like i said right after the reseting the machine it started to print very light... Somehow the reset could have changed some values to factory. Before the reset it was printing fine, black was dense.
I don't know if there's an option called Development Bias Adjust in the machine, i couldn't find it but seems theres some values i could change, like 650 or -650, to increase or decrease the black (saw it on Youtube)...

Development and charge bias are also controlled by ProCon by default. There is a setting to set them a machine to use the manual settings. It is usually for temporary use while waiting for parts like the ID sensor or drum charge sensor.

I wonder what problem forced you to reset...bad story...Forcing the toner feed will not restore the correct developer values. Find the sheet printed with the factory (not default) values and enter them in all the SPs. What are PM counters like?

I wonder how he "reset" it.

I think with "memory all clear"

...with a capital "F"... (hope he knows what the birth certificate is for.)

Not necessarily with a martini B/W machine. The only critical thing lost would be the Laser Diode Power settings, SSP 2103, and the Main Scan Pitch Adjustment. If the label is still on the laser unit, the numbers needed to enter with SP 2115 are on it.

Hi again,
yes i had to reset "memory all clear" with no option for an error (don't remember what was the code) i couldn't turn off... This isn't the first time i did the reset, i remember the light prints issue was fixed by the time after the first reset i did but i don't remember how, was long time ago...
I have this issue with another machine ricoh mp 2003 and i never did the reset on it...starts prints well black but after 50 100 sheets comes light prints. Same happens with the machine that i really need to fix (ricoh 6001).
The method "Forced Toner Supply" works during 50 sheets printed. I need to stop and press again "FTS" to print real black dense again...
I saw some videos on Youtube and some similar ricoh machines have the option "Development Bias Adjustment" "Printing" to adjust the values like 650 to more black or more light to -650, as you can see here:

But mine don't have "Printing" option above the "Development Bias Adjustment", have other options that i don't know what its for ... check my screenshot:

I must say i'm not a pro at the machine, specially when i enter at SP System, i'm learning by using the machine daily for the costumers. I don't have the manual because the machine was a second hand when we bought it years ago. Like i said before, the machine was printing very well before the reset, very probably all the options turned to be "factory".

I just want (if possible) an easy guidelines, possibilities to solve this problem printing. I saw there are some similar issues here in this forum, but to be honest i didn't see any real resolution...


Thanks,

Time to buy a new machine or spend a lot of money on a full service by an experienced tech and a lot of money on parts for this old machine.

I need alternatives, for now... I know this could be fixed but seems no one have patience to help with options, details... I'll wait for a tech.

Thanks anyway.

Did you follow the steps outlined by Slim? If you mean the mp"C" 2003 it is another car of a completely different kind and nothing to do with this one. You need the birth certificate to restore the factory set values or clean the optics, drum group, transfer group, replace the parts outside the PM count (at least developer and drum) and initialise.
