The rotating drum in my HP Laserjet 2500L will not properly rotate to the correct position to load/unload cartidges. Is their a sensor that needs to be cleaned?

    I essentially had the same problem. I never got a useful response from this site. I sent my printer to a local repair shop. After they looked at it, the informed me that it would be cheaper to purchase a new color laser printer than fix this one.

    A friend who is an IT guy told me that the HP carousel design was not on the market for very long because it was not a reliable design.

    I have not had a chance to open up this printer. Based upon how the system works, either the position sensor is bad/dirty or the positioning motor is not working properly. My system started indexing properly after I vacummed out the loose toner and followed this cleaning with a spray-out using a can of compressed air. In the operating mode, the drum would only print yellow. So...though I was able to index the drum to load and unload cartidges, I was never able to get it to properly print. One of these days I'll take the motor out and see if I can find the root cause. Sorry I don't have any better info.

    I have exactly the same problem. In addition, it does not print the yellow color and/or I get totally blank pages. Inside the cartridge compartment (carrousel) there is yellow and red toner all over the place. When I try to unload cartridges (using the cartridge rotator button) I have to try several time until a cartridge stops at the right position. At the end, when I try to insert them, starting with black and blue, after I load the yellow one, I cannot not get the red loaded. It looks like the mechanics have a problem with the gears. Some times I have heard some rattles inside. When I rotate the carrousel with the button and open the top cover while the cartridges rotate, I see that the yellow is not stopping and slightly falling over. As a result the carrousel does not stop at the right position.

Why are lines being repeated down the pages of my hp 9050n?


i assume that the lines are orizontal not vertical? right?
if they are vertical, check imaging unit (drum), you can note the same lines on it plastic belt on the same position.
if are orizontal it can be:
drum: rotate manually the belt (whitout touch it on it surface) and look if it causes the issue.
drum: look at the engage gear on the left (or right) side. it can be damaged (take a look also inside the printer). normally it can cause also paper jam. the lines distance isn't always the same.
transfer roller: search a service manual to see where is located.
fuser: search a service manual to see where is located.

13. Perform the Half Self-Test Functional Check to check all other electrophotographic processes.

14. Replace the transfer roller if necessary.

15. The high-voltage connectors are mounted on the high-voltage power supply (HVPS) PCA and protrude into the toner cartridge cavity.

16. Check the springs for functionality. Clean if dirty; replace if defective or missing.
The HVPS PCA is defective.

17.The DC controller PCA is defecti  There is no drum ground path.

18 Check the drum ground.

19. The laser scanner cable assembly is defective
.
20 The page length and margins are not set correctly for the paper size. Verify that the ribbon connector at J1307 of the HVPS is
properly seated.

21. If the HVPS has been removed recently, verify that the ribbon connector from the DC controller PCA to the HVPS is properly
seated at both ends..

22. Verify that the photoconductive drum is rotating properly. Perform is the drum diagnostic test to visually observe if the drum is rotating.
23. OR using a felt-tipped marker place an index mark on the edge of the drum outside the image area. Turn on the printer (wait for
drum rotation to occur), and then look to see if the drum has
24. moved. If the drum has not moved, investigate the mechanical
and electrical drum rotation circuitry and movement mechanisms.

25. The imaging drum shutter may not be retracting. Replace the imaging drum.

Tape won't load.


This is a problem with the process called 'tape loading' - pulling the tape loop out of the cassette and wrapping it around the spinning video drum, engaging the capstan and pinch roller and reel rotation. With the cover off, observe the behavior when you hit play. (You may need to put a piece of cardboard over the cassette to block external light from interfering with the start/end tape sensors). Assuming this is a basic VCR (no instant start features), you should see: 1. The video head drum begins to spin. 2. the roller guides move smoothly on the tracks, wind the tape around the drum, and stop snuggly pressed against the 'V-stopper' at the end of the tracks. 3. The pinch roller moves into position and presses the tape against the capstan. 4. The tape begins to move and is wound up by the takeup reel. 5. The picture and sound appear on the TV. With a 'rapid or quick start' (or it may be called something else) transport, the tape moves to a half-loaded position when the cassette is inserted. This is at an intermediate position partially pulled out of the cassette but not wrapped around the drum. On VCRs with a real-time counter and/or index search capabilities, the tape will be in contact with the control head. With an 'instant start' transport, the tape will fully load around the spinning drum when the cassette is inserted but the capstan will not engage and no tension will be applied to the tape until you press PLAY or REC. (After about 5 minutes, the drum will stop and it may unload to the half loaded or unloaded position.) Note that for VCRs with a real-time counter and/or index search capabilities, the tape must be in contact with the control head (but not the video heads) for all relevant modes. These VCRs (which include many modern units) must therefore pull the tape at least partly out of the cassette. In all cases, the completion of the sequence results in approximately the same mechanical configuration during PLAY. Several likely possibilities when it shuts down: 1. Everything occurs as above, picture and sound appear for a few seconds, but then the VCR unloads the tape, ejects the cassette, goes into REW mode, stops, or shuts off. Two common causes: The takeup reel does not turn and tape spills into the machine. This is sensed by the microcontroller which aborts record or play and attempts to save your valuable cassette. Most likely cause: old/dirty idler tire. As a test, turn the idler tire inside-out. The fresh surface will now work well enough to confirm this diagnosis and will continue working long enough for your replacement idler tire to arrive. See the section: "General guide to VCR cleaning and rubber parts replacement". The takeup reel is turning properly but one of the reel The takeup reel is turning properly but one of the reel rotation sensors or its electronics is defective. As a test, check to see if the tape counter is changing at any time during the loading and
