Question about Sharp AL-1540CS All-In-One Laser Printer

1 Answer

Cloudy scans I have recently installed a new drum and now my scans(i dont print with it) all come out with a cloudy haze over the entire paper---is it a bad drum?? I cleaned the strip inside the machine with the little, i think, magnetic green handled machine provided tool to no avail--I was hoping not to spend another $80 on a new drum to find out that the problem still exists, but looking like thats the solution after going thru these support problem blogs...

I would start by removing the glass and cleaning the mirror and lens.
Then remove the toner and drum, look inside to the left for an opening about 5/16th of an inch high and 5 or 6 inches wide. That is the laser opening. Get a q tip or soft cloth and with a flash light in hand, clean the laser window. That may also be hazy and dirty.
Then open the right side door, look above the rollers , there is an opening with a very small wire in it. Take a q tip dampened in alcohol and gently clean that wire. It transfers the ink from the drum to the paper. I

Welcome to Fixya

Try to print a document and see if you will be getting same issue. Try to copy a document and see if same thing will happen also. Check if the cartridges are not running out of ink.

Thank you for using Fixya!

Dell 1815dn laser printer prints completely black pages


1. Charge – Print Quality (PQ) -- The charge roller evenly distributes a negative charge on the photoconductor (PC) drum. This evenly distributed charge acts as the film that is discharged (exposed) by the laser to create the latent image.
a. Print Quality effected: Faint, Entire Black background, Grey Fog/Haze
b. Parts Involved:
i. Drum -- A drum cartridge is coated with a photoconductive material that allows electricity to pass when exposed to light. As an example of why this can be the failure, if you leave a drum out in light long enough, you will get dark backgrounds or just black pages. However, drums do wear out over time too; specifically the photo material the drum is coated with. As this degrades, more of the positive electricity on the inside of the drum gets through and grabs toner, as if the laser wrote to every square inch of it. A damaged or defective PC drum can cause black streaks/lines, voids, speckles and various other print quality problems.
ii. Charge Roller Also known as the BCR or Bias Charge Roll. The charge roller pulls double duty. It energizes the outside of the drum with negative energy and as a result it cleans any previous latent images. If the charge roller were failing to energize either due to the HVPS or the charge roller itself, it wouldn’t clean any previous unused toner deposits from the last revolution would start to accumulate and appear on paper more and more causing haze. A missing charge roller causes completely black pages.

iii. HVPS – High Voltage Power Supply -- Responsible for charging components such as the inside of the drum, the charge roller, and transfer roller. If the HVPS does not give enough to the charge roller it can fail in erasing the drum, causing entirely Black pages to be printed.

Bold black lines across the paper when printing,scan or copy not on faxing


I realise this is probably too late for you Janet and you will have bought a new drum unit by now or replaced the printer! The three lines appeared on my print-out from a new drum I installed and after investigation it transpired that there was some toner residue that had dried on the drum (from testing at manufacture stage probably) and reprinted three bold lines on a sheet of A4. The solution is to use a soft piece of cloth and rub the lines off the drum through the gap at the front of the drum unit. The drum can be rotated by turning the gear cog on the side, then once the reside has been removed from the drum and it is clean, the lines will have disappeared. I wouldn't use any solution on the drum, just gentle rubbing should suffice.

New toner cartridge and paper jam


Does this happen when you install the old toner? Is the NEW toner an OEM or compatible? I have run into this problem before on some other Brother all in one models. There is a sensor flag located just below the toner and drum unit. Remove the toner/drum unit, check that the sensor flag will move to back and forth freely. My customer removed the toner and drum unit and threw the drum unit away, not realizing that the toner seats into the drum unit. When they placed just the toner into the printer, it read paper jam. Because the drum unit is part of the paper path, the sensor was not in the correct position.
Try re-seating the toner into the drum unit and then re-seat the entire unit into the printer. Let me know if this helps.
