CLJ 2500 - Caurosel not aligning for dev unit install

[scoobysteve]

Hi All,

I'm working on a CLJ 2500 that has an alignment issue with the caurosel not aligning the groves with the top cover, thus not allowing me to input the toner cartridges.

I seems to align fine for the yellow and black cartridges however it just doesnt do it for the magenta and cyan.

I've had the machine apart and have watched the caurosel turn and i've noticed that the solenoid does kick in at the right time, with the arm of the solenoid hitting the notch in what i would call a cam or gear? however it tends to slip as oppose to release and allow that one extra turn before the arm on the solenoid is able to hook into the 2nd notch (which is located immediately after the first). Because of this extra turn, the groves do not line up.

I have manually released the solenoid so i can put in the developer units however because the magenta and yellow units do not line up, the machine is failing to print the two colours (must have something to do with the e-label) - althought i does detect all four units in the machine.

I'm thinking of replacing the solenoid first (as it will probably be the cheapest and easiest to replace) however if you have any other thoughts or experience with the problem, then please let me know. thanks in advance.

I've align these carousels before, but I don't have a nice technical description of the operation.

It may not be necessary to do it this way, but I removed the laser/top frame to get full view of the carousel. It's relatively easy to jump the gears along the right side of the carousel to get the slots to line up.

If there's an easier way to do this I'd like to hear about it. =^..^=

As a printer tech my basic anwser to a CLJ 2500 repair is.....



Replace the printer!
These were junk to start with.

Just a thought.

Add the 3600-3800 to the pile.

thanks for the 3 sets of advice.... I would much like to get rid of the printer but sometimes the clients just dont want to part with it.

Just a question in regards to the markers on the gears. Is there only one initial mark/pins for alignment as opposed to one for each colour?

If there is only one sets of pins/markers, i would find it strange that the machine is able to line up for two of the cartridges then fail to do so on the remaining two.

anyhow thanks so so much for your advice.. i will try it out.

I don't know about these pins/markers. I just lined it up visually, jumping one tooth at a time. Your description doesn't entirely fit with the symptoms I saw. On the ones I saw all the cartridges were equally misaligned, in equal amounts.

I suspect that the worn carousel bushings could account for your situation. Worn bushings might account for a certain amount of wobbling. Don't forget to allocate 2-3 hours of screwing around to get those bushings installed, especially if you've never done it before.

The labor cost alone might make the repair too expensive. I'd turn it over to sales & give them a chance at it.

thanks again for the help.. i've already spent an hour there trying to identify the problem and if it is going to get more complex, then you are right.. it will be better of getting sales involved. no one wants to pay for the labour costs.

update... i decided to go back and give it another shot... i disassembled the machine re-aligned the pins - it was out about two teeths...

I put it back together ensuring the pins were still aligned and turned it on... without any toner cartridges installed, it rotates and aligns perfectly for all 4 cartridge slots. the minute i put a cartridge in, it does the whole slippage again...

i'm out of ideas on what is causing it but i will try a solenoid and then if that doesnt fix it, i'll get sales involved.... by the time you start quoting assy and labour together it does generally get closer to being uneconomical to repair.

the hardest part is.. do you quote all 3 parts (if certain parts arent contained in the assembly) to the client?

by the time you order one part, change it and it doesnt fix it, then do the next etc, you are already way behind...

ordering all suggested parts will make it not worthwhile.. especially when a certain part is not require and cannot be returned.

Yes that is always a difficult situation. Until you take it apart you're not going to know what you are facing. The bushings are usually the most frequent problem. You tell you customer that it can be 1 of three parts and you won't know for sure until you get into it. Quote them between X and Y. Tell them it will hopefully be less than that, but that you wanted to give them best and worse case scenario. Preparing your customer is a better way of dealing with it. Sometimes they will decline repair and buy a better unit.

As for the part return, I don't know how vendor return policies are in your country, but in the states vendors have what is known as a restocking fee. Unless you are opening an OEM circuit board usually they will let you return it. (I used to save the circuit boards for last for that reason.) The parts you are ordering shouldn't fall into that category. Explain your problem to the vendor when you order and ask about their policy. Make sure you write down the name of the person who talked to you so that you have some recourse against a person promising something and failing to deliver. If they want to retain your business, they will work with you. If not, maybe you should consider another vendor.

Do not forget to quote the labor involved.
The labor alone can be half the cost of a replacement printer.
And quote labor high this is for CYA purposes, it is better for the final invoice to be lower that the quote.

When you remove the top cover there is a solenoid with turn the carousel. Sometimes is sticky and alignment is not possible ,trie to insert a piece of paper between the contact of the solenoid good luck.

Hi All,

I changed the solenoid and that seems to have fixed it... i've removed and installed cartridges several times and the carousel lines up perfect..

Anyhow, i just wanted to update you guys and say a very big thank you to all that has given suggestions as they all helped. so once again thank you.
