Question about Canon PIXMA MP780 All-In-One InkJet Printer

1 Answer

Lots of paper, but practically no printing

When I tried to print today, all that came out was basically a blank piece of paper with a marks which looked like parts of words. 2 colors, magenta & cyan were shown as low, so changed the cartridges with canon cartridges, but still nothing readable comes out, just a few very light black marks, and no color at all.

Thanks for your helps

Are you using a canon? It may be that the printhead is clogged up. Try "clean printhead" option supplied with the driver. Canon printers have separate ink and printhead unlike other brands. You may also replace the printhead if cleaning doesn't help.

Reading no paper paper tray is full


Instructions
  1. Check the display for an error message. If the display reads "Clearing paper from printer," the engine has detected a jam and is attempting to eject the jammed pages automatically. These pages will often be blank.
  2. Check the display for "Performing PRINT/STOP TEST" or "Performing SERVICE TEST." Either of these messages indicates that the printer is going through a test procedure that may eject blank pages.
  3. Reduce the amount of paper in the input tray if the printer is feeding multiple blank sheets at a time. The printer will pull extra pages through if the input tray is overfilled.
  4. Replace the paper in the input tray with the correct size if needed. If the 4600 printer detects the paper as an incorrect size for the print job, it may eject the paper without printing anything on it.
  5. Replace the ink cartridges if certain colors are blank on the page. Replace the black cartridge if printing a black text document that is coming out blank. The printer may attempt to print even if the ink level is low or empty, but will unable to print anything on the page, causing it to come out blank.
  6. Remove the sealing tape from newly installed cartridges. The tape covers the print heads and should be removed before installing the cartridges. If the tape is left on, it will prevent ink from getting on the pages as they print.
  7. Press the "Check mark" button on the control panel to enter the printer menu. Run a diagnostic so the printer can attempt to determine the cause of the blank pages printing. Press the up or down arrow to select "Diagnostics." Press the "Check mark" button. Press the "Down" arrow to highlight "PQ Troubleshooting." Press the "Check mark" button. The printer runs a diagnostic and returns to a ready state when done.

I try to print but the paper comes out blank, I just bought the cartridges today, but I really dont know what happenes.


If you've replaced the cartridges and still the printer comes out with blank paper, then what has happened, depending if it is an inkjet or bubble jet, is that the pump or heating element (in a inkjet it is a pump and in bubble jet the ink is heated up in the tank to produce bubbles of ink that transfer to the paper. When you do get a replacement, hold up a piece of paper printed from a bubble jet printer.

If the printer is not under warranty, then don't bother for the repair.

If it is a laser printer, what may have happened is the wire that charges to the drum in transferring the image to it is not working.

HP Photosmart C4480 won't print


I had almost the same exact problem. Left the printer unused for a month or so, came back, no black ink being printed, even though the level was still sufficient.
What I did, was boiled a small pot of water, and held the black ink cartridge over the steam, about 3-4 inches above the boiling water, for 2 increments of about a minute. Try not to burn your hand or cook the cartridge lol. I wiped the cartridge head with a piece of paper periodically until I noticed a good bit of dark ink on the paper, then gently wiped the condensation off of the cartridge with a paper towel so as not to put a wet cartridge back in my printer. Put it back in the printer and voila!
Works great so far, although I can't vouch for the long term effects of this solution. I did look at the cartridge a bit later to make sure it wasn't leaking, and it wasn't. You have to steam it the right amount of time. I would guess that the printer cartridge head will inevitably dry out again with limited use. I'm hoping that it will keep working though haha. Hope this helps anyone else with this problem.

How do you print No. 10 envelopes?


If you have Microsoft Word go to "Tools", "Letters and Mailings", then "Envelopes and Labels". Usually it will even show you, for your printer, exactly how and where to place you envelope. If you are in doubt, just a blank piece of paper to set it up. Be sure to mark the paper with an arrow so you know which side and which end when into the printer first.

Printing is printing blank sheet of paper


Lots of reasons here but usually it is because the software you are using to print is not compatible with the operating system anymore. Example: you used MS Photo Editor which was discontinued in 2003 and never supported under Windows XP. The one function that is broken is printing...it looks like it printed but a blank sheet of paper comes out. (exactly what you described)

Instead, use MS Picture and Fax Viewer or the follow-on product, MS Office Picture Manager.

If you remove the MS Photo Editor application under Control Panel/Software Programs then your picture files will open with a different (more print compatible and friendly) program.

EPSON TM U200 POS PRINTER


try a self test print(hold feed and power up) if the printer still does not print check the ribbon to make sure it is inserted correctly. If it is still does not print it could be the printhead or pressure setting. you could also try printing with carbon paper to see if the pins in the printhead are striking the paper.

if the printer is still not marking the paper you may need to replace the printhead or printhead cable.

First try to clean the head: Open the top cover and print head, Moisen a small piece of soft, lint-free cloth with alchol and keep wiping the edge of the print head... second, This could also be caused by excess lubricant on the tonercartridge . Print or feed up to 10 sheets of paper through the printer to eliminate the marks. If the problem continues please contact Brother Customer Service at 1-800-284-4329 Monday through Friday, 9:00am - 7:00pm EST, excluding holidays.
