ES4520C code CA00 clr registration error ?'s about adusting

[Desert Rat]

I wish I was more familiar with this model.

The diagnostics take me to a section for trouble shooting this code.

1st Check printer status for toner ratio of less than 5%

Does that mean any dv unit that has less than 5% toner to mix ratio?
Or does it mean less than 5% of the total volume is color?

2nd 08-2692 Prevention of low density. I asked my customer about
temperature changes in the building overnight. They are not using their
heater yet, so the temp changes may be 20 degrees overnight. Both times
the code appeared was in the morning time.
I am guessing that this will cause the machine to compensate for the change?
and 08-2693 sets the number of sheets for judgement.

3rd 08-4546 Invalidating Clr regist control.

This turns off the periodic auto adjustment of the clr registration?
Why would I do this? Is this part of the forced quality control?

4th 05-4720 Abnormal status on Color Regist.

Looks like they subtract the largest # from the list for the first
sensor. Then use the numbers from the list that add up to the
number left after the first subtraction. This gives the second and
third sensor numbers.
Correct?

Any other helpful hints welcome

Thanks

Hello.

In my experiences with CA00 error's, it almost always points towards a problem with the transfer belt, whether it's slipping and not realigning or it just needs replacing. I actually have to replace our showroom 5520's belt because it decided to throw up the very same error on Friday at 5:00pm, which is beer o'clock for us so its a job for Monday. Granted, the belt's life has ticked over a million copies without incident, so it was well due haha.

So in short, I'd be checking out your ITB.

Check the Mag Rollers for even developer coating - if the Rollers are smooth they will not hold the Dev, causing a density issue leading to the CA00 Error, this usually occurs when the EPU/Mag Rollers have done in excess of 170K - the fix is to lightly and evenly sand using fine emery cloth/paper the Mag Rollers, ( the Mash series is far superior to its predecessor the K2 series whereby the the Dev would migrate to the Waste Toner Container), also make sure the Patch Sensors are clean (remove T/fer Belt assy for access).

Re: ES4520C code CA00 clr registration error ?'s about adusting


Aethanite & Canonbundy,
Thank you for those tips. This will be a good opportunity
for me. I will have to change out the black drum because
of all the little specs of toner adhereing to the surface.
They would not easily wipe with a light touch of my finger.
The black copy looked bad little white specs missing toner.
I suspect this is the main cause this time. The mileage is not
that high on this unit.
I will have to make notes from this post for when I go back
to change the drum.

Thank you

I always have found my first clue to tracking the problem by removing the transfer belt right after coding out and look at the patches laid out on it. I will usually find one color that does not have the same density of patch as the others.
Also make the sure the sensors that read the belt are clean. You can clean them while you have the belt out.

Good sugestions all. I should be able to take of this with out
to much stress. Still waiting for the drum tho.

Sort of forget about changing machine settings, what they mean is the values which are required or should be, have been changed - these will usually only change as they compensate for factors such as wear & tear of the consumable items.
Perform a 'Half Tone' print for each colour (which is the same for all Toshiba colour boxes) - hold 0 & 4 > Power On > enter 237 > Start > Stop (pressing Stop will prevent multiple prints of the same colour), a sheet of the selected colour will be produced and will refer directly to any issue with that particular Process Unit - eg. if there is light & dark banding through the print then lightly Sand the Mag Roller (as per my previous Post) this is also assuming the Laser Glasses etc have been cleaned with the Wand beforehand. Replace the DCBs if they are older than 6 months, clean or replace the Grids, if the Drums have banding around them replace them also, then perform a Calibration - hold 0 & 5 > Power On > enter 396 > then 4719 > 4 then Fax Button > place Print on Platen (black edge to L/H side of Copy Glass) > enter 1642 > enter > 70 then Fax Button > place Print on Platen > then enter 1008. Should produce a Spot-On print.

Canonbundy,
Wow, those are good directions. I will look these programs up and
read about them. It sounds like you described doing the auto
gamma set up, after checking for other defects.
I was looking for a way to do a single color from the control
panel and did not find a single color function for the customer.
These have a saw tooth corona right? What do you use to
clean them? A friend said he uses packing foam. Not the peanuts.
But somthing else, the stuff that has a little flex in it.

Thanks Canon bundy
I will have to cut and paste this whole post into a file for later
reference.

Thanks everyone,

Yes, these Units use a Sawtooth Electrode and there is also a drawout cleaner (with a green knob) in the middle of the EPU which has 2 small plastic strips which wipe the tops of the Electrode (mainly for the User) .................nobody uses them, most Techs will remove the cleaner because they can cause more problems from misuse, also the Electrodes (unlike Corona Wires) don't seem to have any real adverse CQ effect.

Happy to help.

Re: ES4520C code CA00 clr registration error ?'s about adusting

Ok I can remove those the first time they cause a problem.

I picked up a call on an ES3530C at a different customer. They only had a spot on the scan for the feeder.
But I noticed that off the glass copy was skewed by about 2-3mm. The customer has not noticed this
yet.
I printed the meter page and it seemed straight on the page.
Also copy from the LCT is to close to the front of the machine as the copy exits. I looked for an adjustment on the guides
or the tray and did not find one. I will have to look through the book for these adjustments.
I remember trying to make an ES 855 make a square print from the glass. It seemed very involved. I was
able to do this but it took hours of reading and adjusting.
Will this be the same way?

Color registration is good, the image is just skewed on the page.
It bugs me more than the customer.


Thanks for your help Canonbundy

If the skew is 'off the glass' then it is reasonably simple to adjust but can be time consuming - there is a large screw on the Second Rate Mirror which is used to adjust the image, turning the screw clockwise/anticlockwise (a small turn at a time) will change the image Skew on the output paper.
