PIXMA TS6420: When I print a page the text is squished to fill 1/3 of the page vertically

fdarmstadt — Sat, 13 Jun 2026 00:43:54 GMT

Good evening.

I purchased a TS 6420 printer that does not print properly. Whether I print from Word, Excel, or Yahoo email, the printed page only fills about one-third of the page as a vertical column and the other 2/3 of the page is white. This is despite the fact that the print preview reads correctly on the screen. Can you please advise what to do? Is it a Settings glitch in the printer? Thank you.About 1/3 prints vertically and the rest is blank.

Quick checks

Paper size: In the app Print dialog and in printer settings, set Paper Size exactly (e.g., Letter or A4) and Scale = 100%.
Orientation: Ensure Portrait (unless you need Landscape).
"Pages per sheet" / N-up: Turn off.

Print from a different source

Print a plain text file or simple web page and the printer's built-in test page (Menu → Setup → Printer Settings → Print Printer Settings / Nozzle Check). If the printer's own test prints normal, issue is on the computer/app/driver.

Reinstall/choose correct driver

On Windows: remove the TS6420 printer (Devices & printers → Remove device), download and install Canon's full PIXMA TS6420 driver package for your OS from Canon's support site, then add the printer again.
On macOS: delete the printer in System Settings → Printers & Scanners, then add it back using the Canon driver (not AirPrint) if available.

In-app/PDF settings

For PDFs, set Scale = None / 100% or disable "Fit to Page". In Adobe Reader try "Print as image".
In Word/Pages, check Page Setup matches the document paper size.

Spooler/print mode (Windows)

Services: restart Print Spooler. Printer Properties → Advanced: try "Print directly to the printer" and/or change the driver’s print mode (e.g., switch between GDI and UFR II if options exist).

Connection test

Try both USB and Wi‑Fi. If printing correctly via USB but not Wi‑Fi (or vice versa), narrow to connection/driver on PC.

Factory reset & firmware

From printer menu: Setup → Device settings → Reset setting / Restore default settings. Check Canon support for latest firmware for TS6420 and update if available.

If none of these fix it, tell me:

OS and version (Windows 10/11, macOS version),
Whether the printer's internal test/nozzle check prints normally,
A photo or precise description of the printed page (top third filled, tiny text, large margins).

Hi! Choice 2 worked in that I removed the printer from my computer and reinstalled it. But I wonder why I had to do this? I have had many "updates" to MS, et al, over the last few weeks and could one of those have had a negative impact on the printer mechanisms? I thank you for your kindness.

A windows update can take any device, printer, scanner out of service and in many cases if the device is old it cannot be be reinstalled. I lost use of a V-100, a very good ten year old Epson scanner after a windows update. I bought a newer Epson scanner, same scanner program but new driver and it installed just fine. So yes an update most likely knocked your printer out of service. I am pleased you were able to restore it to good use.

My darn printer is only a month old (i.e., from date of purchase).
