Bizhub C224e ITB issues

[REGSIS]

Greetings to all

Lately I had 3 similar issues with stripes on ITB leaving a mixed color mark right after stabilization which is gone after few pages. Mark are right at the position of rear IDC sensor. Width is the same as the patch applied at stabilization.
All belts are up to 50k (no more than that). One of them is almost new. Surface of the belt is like new, it's not worn out.

I tried full bleed A3 halftone 128, dozens of pages without marks. Then run stabilization and mark appears, but only at that spot.
For 2 out of 3 customers I saw compatible toners inside (because of last year shortages) and warn the customers that can be the cause.
For 3rd customer only OEM toner is in inside which I sold to them.
All cleaners are good and press tightly on the belt and clean everything when manually turned.
I know ITB replacement is the solution, but it shouldn't happen on low meter belts.
I saw this also on C227 and C287 but that belts usually last less and had at least 150K with visibly worn surface.

A little bit strange, anyone with the same problem?

Re: Bizhub C224e ITB issues

I noticed this problem 1-2 year ago first on 4 series and on 7 series.
I think non OEM toner does not affect on this and it only could be poor quality of cleaning blades.
Few yeas ago it was normal for ITB on 4 series to have life over 250k and working ok , rarely see this cleaning problem.
Luckily i found some replacement cleaning blades from China and it works ok for about 50k and it is ok for the price less than $10.

Did it look anything like the attached?

C287 Mark.pdf

We had it on a C287, the colours went to sh1t as the patch couldnt be read properly.

Intially we cleaned the transfer belt, blade and cleaning section. That fixed it for about a month. It returned, this time cleaned all those items again but checked the vertical chute/waste toner pipe which must have been blocked and causing it to back up, then cleaning failed. 2 years since then no problems.

Obviously cleaning blade doen't do its job. But why only on this point and why only after stabilization. Hundreds of pages between 2 stabilizations were fine.

Cleaning issues usually starts at 250k-350k.
40-50k is too early.

Re: Bizhub C224e ITB issues

I did not noticed it happened only at stabilization, it is more random for me.
I noticed one pattern, this cleaning problem occur more frequent at morning and during winter when temperatures are lower.
This could be maybe explained by lower temperature cause rubber on cleaning blade is get more hard and lose ability to adapt for belt surface.
Btw i dont have idea why problem in most cases occur on position on the belt just where IDC located...

There are 3rd party cleaning blades available that cost peanuts & do the job very well.

Got a source?
Easy to find, but I have had concerns regarding quality

Particulary on one machine it makes me crazy.
On last visit I replaced cleaning blade (CET) and problem
returned after a day.
I suspect at NON OEM toners filled in original bottles.
They are sold as OEM (full) although OEM half bottles are the only OEM option for a year now.
First I changed K toner and noticed good quality halftone 64 & 128 after 15 days (when old toner run out).
Before, K haltones were grainy!
Y seems good, M & C still grainy; I suspect they are the reason for this problem. M&C toners are now replaced, still old toner in hoppers and dev tanks.
I'm going to vacuum toner hoppers M&C and empty dev tanks by making 255 halftones.
Also grid voltages for M & C are above 600;
K & Y are normal.
If all fails, I'm going to replace ITB again.

Re: Bizhub C224e ITB issues

My assumption that NON-OEM toner filled in OEM bottles caused this problem turns out to be correct.
On one machine I vacuum toner hoppers and output halftones to empty dev tanks. Imideately after toner from new bottles filled dev tanks, halftones were not grainy anymore. There was no color stripe anymore, and no P codes after stabilization.

On the other machine I just changed suspicious toners (with grainy output) I didn't vacuum hoopers. It takes about 15 days (2k color outputs) for machine to stop reporting P codes. It takes a while for old toner to be changed with new one.Yesterday, a month after last P-code I checked halftones 128 and the were perfect and not grainy anymore.

This NON-OEM was packed in OEM bottles and cardboard boxes i looks dentical to OEM. I noticed only 1 small difference. Label on black cap had font a little bit greyish - not white as on OEM bottle.

Great and thanks 👍 for coming back with resolution.
Absolute respect brother for your job not only in this case.

Re: Bizhub C224e ITB issues

Here are some differences between OEM and those LOOK LIKE OEM bottles

White on label is not clear white but a little bit gray.

Distance between grooves are pretty similar but not identical.

Bottom of the bottle has wider line from side to side.

It's hard to judge but looking on these 2 bottles it seems like that NON-OEM cyan is a bit darker and stabilization is not done correctly. Furthermore it has larger toner particles resulting in grainy looking halftones.

I have nothing against aftermarket toners which are sold as aftermarket, but this is a fraud.
Those are sold as OEM with OEM price, filled as full bottles although OEM color toners are still sold half filled.
