#MG5750 suddenly printing blank sheets.

[PeteBa]

Hi - I'm hoping there's a simple (& fixable!) reason why our #MG5750 should have suddenly, between print jobs (5mins after the last perfectly OK one), started printing blank sheets. No gradual fading of colours, no one colour missing, all others OK, and same result on a self test, so it's not computer related. Tried a deep clean, to no effect, all cartridges nearly full apart from one low-ish one.  Firmware up to date.

One strange thing: on one occasion when I asked it to carry out a nozzle check, it printed the usual blank sheet, apart from, halfway down:

8401-8450 Pages

Ver. 2. 060

Does that mean anything to anyone?

Thanks

To determine if this is being caused by the printer or by your device settings, print a nozzle check from the printer panel:

To run a nozzle check on a Canon PIXMA MG5750 from the printer's control panel, load A4 or Letter paper, press and hold the Paper button and Power button together, release the Power button first, then release the Paper button when the nozzle check starts.

Hi - thanks for the speedy response.  Unfortunately, I didn't make it clear enough that the self-test (ie nozzle check) was carried out from the printer control panel (though using the options on there - I'm not aware of a 'paper button').  The computer is not connected in any way.

Did the printer eject an extra sheet of paper after it printed the nozzle check? The end of a nozzle check is the page numbers, the first number is when a cartridge was installed and the second is the current page number. The nozzle check seems to be okay, so that  indicates that somewhere a page setting is in conflict with your printer settings.  

Verifying Page Settings on Canon MG5750 Printer

To ensure your Canon MG5750 printer is set up correctly for printing, follow these steps to verify the paper settings.

Check Registered Paper Size and Media Type

1. Access Printer Settings:
   • Go to the printer's control panel.
   • Navigate to the settings menu.

2. Verify Cassette Information:

   • Check the paper size and media type loaded in the cassette.
   • Ensure that this information matches what is set in the printer driver.

Confirm Printer Driver Settings

1. Open Printer Driver:
   • On your computer, open the printer settings through the Control Panel or printer management software.

2. Check Paper Settings:

   • Look for the paper size and media type settings in the printer driver.
   • Make sure they correspond to the paper loaded in the printer's cassette.

Troubleshooting Mismatches

If there is a discrepancy between the cassette settings and the printer driver:

• Adjust Printer Driver Settings:
  • Change the settings in the printer driver to match the loaded paper.

• Replace Paper if Necessary:

  • If the settings cannot be matched, consider replacing the paper in the cassette to align with the printer driver settings.

Summary of Steps

Hi again.  Thank you for a very full and explanatory reply.  However, I'm afraid I think I must be not explaining myself clearly.  The nozzle check gives one completely blank page, except for the one occasion - not repeated - when it printed that text halfway down the page; again, apart from that text, the single sheet was blank.

There can't be a mismatch between the driver settings and the printer because a) this happened immediately after a successful print run, and before we attempted another, with no change of settings, and b) I am not involving the computer at all - it's nowhere near - and am just asking it to do a nozzle test (and deep clean etc) from its own control panel.  I also tried a photocopy from the control panel - again, the printer went through the motions, sounded like it was printing perfectly - but nothing at all on the paper. That's something I haven't mentioned before - my apologies - it doesn't just eject a sheet of paper, it does actually sound as though it's printing whatever it's been asked to.

Since it happens from the printer panel too (and the nozzle check looks correct), the ink is fine—the printer is almost certainly mis-feeding/mis-registering the paper or the page-size/margins settings are wrong.

1. Reset paper settings on the printer

• In the printer menu, set Paper size to what you’re using (Letter or A4).
• Set Paper type to Plain paper.
• Save/confirm, then print the nozzle check again and a test page.

2. Paper feed test

• Load one sheet only (not a stack), centered, guides snug.
• Print a page. If it prints correctly, your feeder/stacking is the issue (stack too high, uneven, dust, guides).

3. Clean the paper path

• Remove the paper; look for any debris.
• If there’s a document feeder (ADF) or pickup rollers, wipe gently with a slightly damp lint-free cloth; let dry.

4. Check for “borderless” / “fit” / “full page” mode

• If there’s any option like borderless or “full bleed,” turn it off and retry.

Reply with: are you on Letter or A4, and does the print land only in the bottom half every time or does it shift (sometimes higher/lower)?

Hi again

I'm sorry, I really don't know what is going on here.  You say 'the nozzle check looks correct';  no, it doesn't.  I don't wish to appear ungrateful, but you seem to be ignoring what I have said from the outset - the nozzle check produces a blank sheet of paper, nothing on it, no colours, no patterns, nothing.  Apart from that one time when it printed that brief bit of text halfway down the page, no ink has appeared on the paper, not matter what test or maintenance task I ask the printer to carry out (from the control panel, without any involvement by the computer).  I've checked the paper settings, and it thinks it's got A4 plain paper in the cassette, which is what it does have.  Nothing fancy like a document feeder.  And it did this between 2 identical jobs - we asked it to print 20 copies of a document, as we had already successfully done a number of times (we wanted 120 altogether), asked it for the next 20 - nothing.

Okay, now that I have clarification, if no color being printed during a nozzle check then this usually indicates clogged printhead nozzles or dried ink; which can cause the printer to spit out blank pages. Run the printer's built-in cleaning cycle and then reprint the nozzle check pattern to verify if the issue resolves. If you have already performed a cleaning then perform a  deep cleaning then run a second deep cleaning, if the nozzle check still is not correct. Multiple cleanings do sometimes fix this kind of issue. . Then run another nozzle check, if it still will not print color then unfortunately your printer head is malfunctioning.
