[PICS] What needs replacing here?

Re: [PICS] What needs replacing here?

Before you spend a lot of money try this:
Wand the primary charge wires and laser slit glasses, then print off these images and post the results.

130K is not really a lot on the developing units. As long as you're using OEM toner they should be still serviceable.

Dirty laser slit glasses could cause a lot of your voids.
The lines seen best in orange are probably caused by the magenta drum unit.
The images you show indicate to me that you'd be best to start out with the black and magenta drums, and a gradation and stabilization.
Once you've done that much you (read: We) can diagnose it further, without spending a lot of money.
=^..^=

So true we are skipping the most basic of maintenance.
Good advice.

Print some half-tones and post that.

Hehe let it rip.
Hey i do use chips by the way and fuck me for doing it.
My non contract customers has no problem with me using them to get all the value out of the parts.
Phil has the 6th sense for bullshitters the gift comes with a price.

Hey OP. Buddy do you want to fix it yourself?
If you don't like taking stuff apart there is a good chance that you will find a way to screw it up.
Have you considered hiring a tech?

Tech is next to impossible with my city on full lockdown, all businesses closed again I have bought 4x black drums and CMY chips to screw onto them.

Thank you, I have done the test you've provided, the forum won't allow me to upload so I have hosted it on GDrive

The quality is not great but you can see the lines. It's hard to see from the scans but with the black graduation I can see yellow, magenta and cyan lines mixed in with the pixels? Slightly visible on the page 7 with the black.
Please note that these were printed on round label paper so excuse the circles

OEM toner is being used with this printer.

Re: [PICS] What needs replacing here?

I was wondering about the circle pattern.

Yes all the drums are bad. I never saw the point in re-chipping old drums. Start there, and the gradation and stabilization. Use good quality 96 brightness paper on you calibrations. It will make a huge difference in the results of the calibrations. =^..^=

Perfect! Purchased 4 black drums and the chips to put on them.
Appreciate the help and will keep the thread updated - Now to have a rant at the seller tomorrow and start the PayPal claim.

but you are not trying to mislead your customers or sell the machines as "refurbs"
big difference

Yes very true. Doing that can only hurt your reputation.
Re-chipping the units works better than to just enable life stop.
Its good practice to remove the units to inspect and clean them. Getting the toner dusting off of the charge grids help.
Also helps to reset the aging compensation. From there increase your drum charge a bit.

For customer that sign up for high color quality they get what they pay for. Parts gets replaced at service time.
That recipe make for a very trouble free machine for sure.

The money that can be saved dealing with those troubles brings the printing cost down a bunch.

Re: [PICS] What needs replacing here?

Yes you are on the right track.
4 x drums and remember to clean the laser glass after installing.

Its a user changeable part and replacing the chips will save you a bunch.
Somewhere you got good advise.

Re: [PICS] What needs replacing here?

Hi, change the drums. The replacement is not so complicated, in some cases we have it sent directly to the customer and he replaces them. On Youtube you will find tutorials.

Re: [PICS] What needs replacing here?

fuck the chip and all who use them.
replace the damn worn consumables and fix the damn thing!

When I worked at a tighta$$ dealer I quickly realised such devices only serve the purpose of increasing the wealth of the dealership owner. I don't like to lie to people and we were told to go around to customers who had requested imaging units etc to reset them instead. The excuses we were asked to use were outright lies and we were expected to be convincing.

And for what?

For the dealer principal to show up in a new Ferarri the week after telling us we cant afford pay rises this year.

I'm with you Synthohol.

lucky the 8 series have a software switch to just disable the consumables screen instead.

and it wasnt a new Ferrari it was 2nd hand haha

Re: [PICS] What needs replacing here?

Just wanted to take a moment to clarify my stance on this. If you are replacing the drums with black drums and putting a new chip on it I have no problem with that only when people replace the chips to avoid replacing a worn or timed out consumable

Agreed. We tried rechipping when it is fair, practical, helpful, honestly, openly done with customer informed. Problem with these 4 series is not too much after the drums are past yield they will streak and eventually pull developer, sometimes pulling enough dv out to run spiral designs, near empty mag roller until the customer reports freaky waves or tcr levels cause a code. Then you have to rescue or replace a dv unit.
Just do exactly as blackcat4866 says.
Clean laser slits and wand down the chargers. Since the drums are probably going to be replaced anyway, I have no problem telling the user to (take the drum outside in the shade) get a can of air and stick the straw in the gap between the plastic/mylar and the drum & blow off the charger screen grid under the drum to help clean the charger where the wand wont. It will help reduce maybe 50% or more of those lines. It will buy you some time but best to buy the 4k oem drums and chip cmy. RE-clean the laser slits underneath after any drum install. Instant success. DV's should be good for a lot longer.

BTW, KM has riveted the K chip on now, so careful removing the rivet. If you cut off the top, the rivet shaft will fall into the charger and cause hell. Best to get a 100 watt solder gun, touch the rivet for just a few seconds and lift the chip with a flat blade screwdriver. The rivet will melt its way out the top. Smear enough plastic back into the hole to screw in your new chip, or get the right size screw to do so. You can use the old drum's charge cover screws. they are perfect. Some people double stick tape the chips down.

Keep yer powder (& paper) dry!

Re: [PICS] What needs replacing here?

Second post(Replied to the wrong thread first)

Thank you for to all those that helped! All units have been replaced, rechipped from black unit and everything is spot on.
AMAZING! Not felt this happy for a long while.

Apart from a burnt finger from my solder iron, everything went smoothly.
I will be donating to the forum at the end of the month when my salary hits.

Re: [PICS] What needs replacing here?

You'll get used to the burns from the soldering iron. You don't even feel them after a while.

Congratulations on your success. =^..^=
