Question 1

How can I find out the number of sheets printed with a Canon MG5750 printer?

Accepted Answer

The Canon MG5750 printer does not have a built-in function to directly display the total number of sheets printed. However, here are some methods to estimate or obtain this information:

1. Using the Canon software installed on your computer

If you have installed the software provided by Canon (such as Canon IJ Printer Assistant Tool), it is sometimes possible to access usage statistics, including the number of pages printed. Open this software and look for a section related to status or statistics.

2. Printing a configuration report

Some Canon models allow you to print a configuration report that may contain information about printer usage. To do this:

Turn on the printer.
Press the Menu or Setup button depending on the model.
Look for an option like Configuration Report or Status Report and start the printing.

Check this report to see if the number of printed pages is mentioned.

3. Checking via the operating system

On Windows, you can:

Open the Control Panel > Devices and Printers.
Right-click on the Canon MG5750 printer and select Properties or Printing Preferences.
In some cases, the Services or Maintenance tab displays usage statistics.

Note that this method depends on the installed driver and may not be available.

Note

If none of these methods provide access to the precise count of printed sheets, it may be useful to manually track the number of printed pages via the software or use third-party print management tools.

Question 2

How to clean the print heads on a Canon MG 7750 printer?

Accepted Answer

Regular cleaning of the print heads on your Canon MG 7750 is essential to maintain optimal print quality. This printer has two cleaning levels accessible directly from the touchscreen: standard cleaning and deep cleaning.

Standard print head cleaning: Start with this procedure if you notice white streaks, missing lines, or uneven print quality. First, ensure that the printer is turned on and that you have loaded a sheet of plain A4 or Letter paper into the tray. Access the menu by touching the Setup icon on the touchscreen, then select Maintenance. Next, touch Cleaning and confirm by pressing Yes. The cleaning cycle lasts about 2 to 3 minutes, during which you should let the printer operate without performing any other tasks. Once completed, the printer will prompt you to print a nozzle check pattern: accept to verify that the cleaning has improved print quality.

Deep cleaning: If standard cleaning is not sufficient, perform a deep cleaning. This operation uses more ink and is more intensive. Go to Setup > Maintenance, then touch Deep Cleaning and confirm by pressing Yes. This operation also lasts 2 to 3 minutes. A nozzle check pattern will be printed at the end. If you need to restart a deep cleaning, wait at least 24 hours, as this procedure consumes a significant amount of ink.

Important recommendations: Always check that the six individual cartridges of your Canon MG 7750 (PGI-550PGBK for pigment black and CLI-551 for other colors) are properly installed and contain enough ink before starting the cleaning. Only clean the print heads if necessary, as each cycle uses ink. Never attempt to rinse or wipe the FINE print head of this printer manually, as you risk damaging it. If the problem persists after two cleaning attempts, turn off the printer and try again the next day. If the quality remains unsatisfactory after these steps, contact the Canon service center, as the print head may be damaged.

Question 3

How to identify and replace the paper feed roller on a Canon PIXMA MG3650 printer?

Accepted Answer

The paper feed roller on your Canon PIXMA MG3650 is an internal component located inside the printer, in the paper feed tray. It is a rubber part that comes into direct contact with the paper to advance it towards the print heads. Unlike ink cartridges, this roller is not designed to be replaced by the user and is not part of the standard consumable parts.

According to the official manual, if you notice that the paper is not being fed correctly (frequent jams, slow or irregular feeding), the roller is likely clogged with paper particles or dust. Before considering any intervention, you can clean the feed roller using the official Canon procedure. Warning: this cleaning operation gradually wears out the feed roller. Only proceed if the paper feeding issues persist and are truly bothersome.

To clean the feed roller, follow these steps: 1) Ensure the printer is powered on and remove any paper from the feed tray. 2) Open the paper output tray. 3) Press and hold the Stop button until the Alarm indicator blinks seven times, then release immediately. The roller will turn without paper to clean itself. 4) Once the roller has stopped turning, close the paper output tray and insert a sheet of plain A4 or Letter size paper into the feed tray. 5) Open the extension and the paper output tray again, then deploy the output support. 6) Press and hold the Stop button again until the Alarm indicator blinks seven times. The paper will be ejected once the cleaning is complete.

If after this cleaning the paper feeding issues persist, the feed roller is likely too worn and needs to be replaced. In this case, only an authorized Canon service center can access this internal component and carry out the replacement. Contact Canon support with the serial number of your PIXMA MG3650 printer to obtain a repair estimate or warranty coverage if your device is still covered.

Question 4

What does the message "Toner almost empty" mean on the Canon iSensys MF4750 printer and how can I resolve it?

Accepted Answer

The message "Toner almost empty" on your Canon iSensys MF4750 printer indicates that the toner level is low and that it will soon be necessary to replace the cartridge to continue printing without interruption.

What to do when this message appears?

Check the toner level: The printer's control panel often allows you to check the exact remaining toner level.
Prepare a new cartridge: Purchase a toner cartridge compatible with the Canon iSensys MF4750 model. Ensure that it is brand new and undamaged.
Replace the toner cartridge:
1. Open the front cover of the printer.
2. Gently remove the empty toner cartridge by pulling it towards you.
3. Take the new cartridge out of its packaging and remove the protective seals (tapes, plastic films).
4. Insert the new cartridge into the printer until it clicks into place.
5. Close the printer cover.
Test the printing: After replacement, print a test page to check that the printer is functioning normally and that the error message has disappeared.

By following these steps, you ensure optimal operation of your printer and avoid interruptions during your printing tasks.

Question 5

How to resolve the issue of no color printing on a Canon GX1050 multifunction printer?

Accepted Answer

If your Canon GX1050 printer is no longer producing color prints, start by checking the ink levels of the color cartridges (cyan, magenta, yellow) via the indicator located on the front of the printer. If a cartridge is close to the minimum, refill it by opening the ink cartridge cover, unlocking the relevant cartridge, and pouring ink from the supplied bottle into the refill port. Insufficient ink completely prevents color printing.

Next, print a nozzle check pattern to diagnose the condition of the print head. From the HOME screen, go to Setup > Maintenance > Nozzle Check. If the pattern correctly displays all colors (cyan, magenta, yellow), proceed to check the print settings. If a color is missing in the pattern or if lines are absent, a print head cleaning is necessary.

Perform a standard cleaning by going to Setup > Maintenance > Cleaning, then confirm. Wait for the operation to finish and print a new check pattern. Before cleaning, ensure that there is enough available space in the maintenance cartridge; otherwise, install a new cartridge. If the problem persists after this cleaning, wait 24 hours and then perform a deep cleaning via Setup > Maintenance > Deep Cleaning.

Also, check the print settings on your computer. Before printing, ensure that color mode is enabled in the Canon printer driver preferences and that you have not mistakenly selected black and white or grayscale printing. Check the properties of the document to be printed and confirm that the source document actually contains colors.

If you are printing via USB, reconnect the cable directly to the printer and the computer. If you are printing over a network, check that the Wi-Fi connection is stable. Update the Canon driver by downloading it from the official Canon website.

If after all these steps only black prints and not colors, and the check pattern does not show colors despite the deep cleaning, contact Canon support as this may indicate a defect in the print head or cartridges. Never use cleaning frequently as it quickly consumes the remaining ink in your printer.
