Here a short run down on it:

Common on this type print engine. Your carousel is out of index. Repair requires removing all toner cartridges and printer covers. Big black carousel gears have index marks, one on each side. Trip the solenoid carousel brake at the top left of the rotary drive assembly by lifting the solenoid flap to free manual carousel rotation. Bring the yellow slot to the front, facing you to achieve rough indexing. Look for the two white pins of the white carousel drive gear, one pair on each side. Rotate the carousel to where the two pins, which face inward, are at the bottom. The mark of the carousel gear should be between the two white pins. Chances are it is a tooth or two out of index on one side. To reindex, push the black carousel gear inward and the white drive gear outward to skip a tooth. Recheck, reassembly, and have fun.

Hope that helps you.

The previous way of realigning will work but you will be there for an hour. There is a much easier way that takes less than a minute but easier to show or find a good tech. I believe there is probably some video support out there how to do it but if you don't know what you are doing, take it to a shop.

Hp 1320 drawer stuck


hi

The paper tray has a small lock at the bottom of the tray which is broken or dislocated hence try to fix it if its dislocated or you may have to replace the try itself. But still you can use it by adding paper to the full of the tray's capacity and pressing it gentelly downwards and push it back into the printer.

Toner yellow, magenta and black lights are flashing. cannot put in magenta toner as the "arrow" positions are not at the right places.


This sounds like the carousel in the printer has gone out of alignment. This is usually caused by using old generic toner cartridges. ( the roller on the toner cartridge seizes and causes carousel to go out of alignment. )
There are other easy fix instructions on here to realign the carousel.

2550L carousel won' t rotate when I push the button. Need to get the cartridges out to put in a newer one that I bought.


This is usually caused by generic toner cartridges. The only way to turn the carousel is to take the top cover off and then manipulate the solenoide on the top right hand side of the printer. This allows the carousel to turn to where you want it.

Service required E527


E527 indicates a developer home position error. With the front cover closed you should be able to freely rotate the cartridge "carousel" from the top with the PCU removed. If it does not rotate smoothly then something is broken and the printer will require stripping completely and the broken parts replaced. If this is the case then it is unlikely to be economically repairable. If the carousel does rotate freely however, then it is one of the following: Either the MCU (engine) Board itself is faulty, there is a wiring fault or the Sensor Rotary Home Position is faulty/dirty. The sensor is the first and most obvious thing to check but it requires taking off the L/H cover and removing the Low/High Voltage power supply board to get at it. I would recommend getting someone experienced at repairing printers to do this, but if you really want to give it a go then follow this link;

The color is faded on the left side of the page printer, what is the possible cause or solution?


From the service manual:

If the light printing is on the left side of the page, the carousel might be dislocated.

Solution: Verify that the print-cartridge carousel drive teeth are aligned correctly. If the teeth are aligned correctly, replace the print-cartridge carousel.

The machine is telling you that there is something wrong with one of your toner cartridges. If you recently installed a remanufactured cartidge the builder didn't replace the smartchip on the nose. If your using OEM (HP) orginal cartridges you may have got a power surge that has knocked out the memory on the toner cartridge.

Try to bypass the error. Attempt to print a "Supply Status" page from the printer. It will tell you exactly which one is at fault.

Here's a link for a free service manual for the printer that could also be of some assistance.
