[Misc] When You do a PM Preferences?

[Vulkor]

When you do a PM and replace the drum, drum blade, charge roller, developer and filters is there a preference to which Sp should be initialized first. I'm not asking for SP's here. I've got manuals and done a ton of PM's, but always wondered if I could improve them.

Do you

ID/Drum Init First

or

DV Init First?

[teebee1234]

I would do the dev initialization first to lock that in. Running ID initialzation first runs the risk of either toner being depleted or more toner being dumped in the dev unit during that process (patches being placed on the drum). Though overall I don't think it affects it. that much

[Vulkor]

What I thought as well. Also I put the paper over the Dev unit entrance like it says but that always leaves a toner mess when I pull it out. The Service manager just leaves the toner bottle out of the machine while he does the PM. After he is through Initializing the Drum and DV then he put's it back in.

For me its dev first then ID as the ID is image density so i think you would not get a true reading for the ID unless the dev is mixed correctly thus throwing out all the other readings like VSP etc.

When you say mixed correctly you mean WITHOUT Toner right? Since service manual specifies block toner entry into DV unit during initialization.

it is my understanding that there is sufficient dev/toner mix in a new bag to gain a correct td reading. Therefore sp2801 should be done first before process control etc, there are various ways of attaining this state depending on the machine model. This should be followed by id initialisation. Incidently just removing the toner bottle wont help as there is usually plenty of toner in the toner supply path or hopper(depending on model).

[Vulkor]

AABARNES1 - Yeah that is what I try to tell the guy. Thus the reason Ricoh has you place paper over the DV entrance.

After thoroughly cleaning the pcu and dv unit, and installing developer, I cover the opening between the two units, then do 2801, uncover, and then do 2805. I then do a 3-002-002 ID sensor setting and then check my voltages. Then, print out an SMC report to check the quality, vs copying a test chart.

ive done the dev with and without covering the hole and its made no differnce to the result, as said before there is enough toner in the new bag of dev to get it started which is why i believe you should do a dev initialization first to charge the dev particles.

[zed255]

I always reset all bias voltages to the default values first, then initialize developer SP2801 and SP2805, and finally initialize the ID sensor. I vacuum out the machine very thoroughly and don't worry about covering the toner entrance to the developer unit. Then I typically run about 50 to 100 copies before making any judgement on copy quality.

[Vulkor]

Some of the new ones also have the SP for GrayScale Initialization. Also I have Noooooo ID what the voltages are supposed to be and which ones are wrong what they may indicate. Was never taught that.
