Fuzzy print is mostly related to 3 items in your printer. 1 the toner cart. 2 fuser. 3 transfer roller. A fuser replacement is a normal fix for this problem. Check your PM kit status by printing a supplies status page. A PM kit will have a fuser, transfer roller and feed rollers. If the PM level is low ,order and replace kit. If not you may want to get a new fuser

Jam at exit open door a


Could be a fuser problem, but could also be very poor quality toner cartridge(s). If a remanufacturer/compatible maker uses the wrong toner powder, it can have the wrong characteristics.


I've seen these printers with poor quality cartridges able to print a page with very little toner coverage OK, but jam EVERY page that has much real 'density' of toner. Even the configuration page on these printers has a solid band of red 5mm or so wide across the lower part of the page. Poor toners - where the fusing temperature is incorrect for this printer will cause the page to jam in the same place in the fuser EVERY TIME.


The cure - Genuine Xerox toners, or GOOD QUALITY remanufactured toners from a reputable source.

This might be a cartridge issue. You should also ensure that you have the media type set to envelope as this slows the pirnter down and provides best print quality. If the toner cartridge is not an OEM it might me the issue as well as toner quality on remans varies dramatically.

I am having print quality issues on a Dell 2135cn MFP - print on the left side of the page is light.


Try removing the toner cartridge and gently rotating it back and forth. Often the toner will bunch up like a snow drift and where there is little toner you'll have light or no print. If that doesn't do the trick try another toner cartridge.

Smasung ML2510 Laser print quality poor especially on graphics


Full isn't always the answer, in order to refill a cartridge properly you need to also replace the cleaning blade inside. The blade wears out and doesn't clean the drum properly and also lets toner leak all over. Your best bet is a new OEM cartridge, or put a new cleaning and Dr. blade in yours.

It prints vertical lines where the text is.


check your drum unit. The toner cartridge mounts into the drum which can be permanently charged causing a constant streak to occur.

Solution:
Remove the toner and drum unit. Clean them off with a non-fuzzy non-rough cloth or paper towel. Pay particular attention to where the streaks are in relation to the toner cartridge and drum. If you clean it off and you still get streaks check whether they transfer from the toner or just from the drum.

There may be a way to discharge the drum, otherwise you need a new drum.

Cleaning the printer eliminates or reduces these problems. Use the following steps to clean the paper path and print-cartridge areas: 1. Turn the printer off and unplug the power cord. 2. Open the top cover. Figure 1: Top cover opened example 3. Remove the print cartridge. Figure 2: Print cartridge removed example CAUTION: To prevent damage to the print cartridge, do not expose it to light for more than a few minutes.Be careful not to touch the transfer roller (the black, rubber roller located underneath the print cartridge). Skin oils on the roller can cause print-quality problems. 4. With a dry, lint-free cloth, wipe any residue from the paper path area and the print cartridge cavity. Make sure not to touch the transfer roller with fingers, as the oil can contaminate the roller, resulting in print quality defects. Figure 3: Paper path area and print cartridge cavity example 5. Reinstall the print cartridge and close the top cover.

Plug in the power cable and turn on the printer. Cleaning the fuserback to top of page Run the printer cleaning page to keep the fuser free of toner and paper particles that can sometimes accumulate. Accumulation of toner and particles can cause specks to appear on the front or back side of print jobs. To ensure optimum print quality, HP recommends using the cleaning page every time that the print cartridge is replaced or on an automatic pre-established interval. The cleaning procedure takes about 2.5 minutes to complete. A message (either CREATING CLEANING PAGE or CLEANING) appears on the printer control panel display while the cleaning is taking place. NOTE: Use plain paper to print the cleaning page. Please note that this is a two-step process. First print out the cleaning page using the following directions, then follow the directions on the cleaning page itself to reinsert it back into the printer to perform the cleaning. Use the following steps to run the cleaning page: 1. If the printer model includes a duplexer, open the rear output bin. 2. Press example(Select button) to open the menus. 3. Use example (Up button) or example (Down button) to scroll to CONFIGURE DEVICE, and then press example (Select button). 4. Use example (Up button) or example (Down button) to scroll to PRINT QUALITY, and then press example (Select button). 5. Use example (Up button) or example (Down button) to scroll to CREATE CLEANING PAGE, and then press example (Select button). 6. Perform the following to complete the cleaning process. 1. Remove all paper from Tray 1. 2. Use example (Up button) or example (Down button) to scroll to CONFIGURE DEVICE and then press example (Select button). 3. Use example (Up button) or example (Down button) to scroll to PRINT QUALITY and then press example (Select button). 4. Use example (Up button) or example (Down button) to scroll to PROCESS CLEANING PAGE and then press example (Select button). 5. Load the cleaning page created in step 5 above into Tray 1 with the print side down and the arrow towards the printer. 7. If the printer model includes a duplexer, close the rear output bin.
