Before you start

Do not run head cleaning cycles repeatedly. Each one consumes a meaningful amount of ink, and running five in a row can empty a cartridge without clearing a stubborn blockage. Two or three, then leave the printer overnight, is far more effective than a dozen in an hour. Anything involving opening the printer beyond the cartridge access door, or removing a printhead, should follow your model's own instructions — printheads are fragile and some are not user-serviceable at all.

The self-test page, first

Almost every printer can print a test or configuration page from its own control panel, with no computer involved. On models without a screen it is usually a button held for a few seconds; the manual gives the exact combination.

This single page splits the problem in half.

What the printer's own test page tells you A test page printed from the printer's own controls bypasses the computer entirely. If that page is blank the fault is inside the printer. If it prints correctly the printer is working and the problem lies with the computer, the driver or the document. Print a test page from the printer Blank too The fault is inside the printer. Nozzles, cartridges, seals, drum. The computer is irrelevant. Prints fine The printer works. Look at the driver, the app, or the document itself. Thirty seconds, and it removes half the internet's advice from consideration.
Everything downstream depends on this answer. Get it before changing anything.

Two related tests worth doing at the same time: print from a different device (a phone, if the printer supports it), and print from a different application. If only one app produces blank pages, the printer and driver are both fine and the problem is in that app's print settings.

Reading the nozzle check

Inkjets can print a nozzle check pattern — a grid or set of stepped lines, one block per colour. It is more informative than a test page because it shows which nozzles are firing.

Run the nozzle check after each cleaning cycle rather than cleaning blindly. It tells you whether the cleaning achieved anything, which is how you avoid wasting half a cartridge.

Dried nozzles, which is most of it

Inkjet nozzles are extremely fine. Ink left sitting in them dries, and dried ink blocks them. This is the dominant cause of blank pages with full cartridges, and it has a characteristic history: the printer worked, then sat unused for weeks or months, and now prints nothing.

What actually helps, in order of how much you should try it:

If several thorough attempts over a couple of days change nothing, the blockage is likely beyond what the printer can clear itself. On models with a user-replaceable printhead that is a part; on models where the head is built into the cartridge, a new cartridge solves it; on models where it is integrated into the printer, that is often where the economics stop making sense.

Tape, strips and seals

This sounds too obvious to mention and it is one of the most common causes of a brand-new cartridge printing nothing.

If the blank pages started with a new cartridge, take it out and look at it against the instructions in the box before doing anything else.

Cartridges, chips and seating

Laser printers fail differently

No nozzles, so no drying. Blank pages from a laser have their own short list.

One useful laser-specific check: if the page comes out blank but warm, the fuser is working and paper is travelling correctly, which points at toner or transfer rather than a mechanical fault.

When the page really is blank

If the printer's own test page is perfect, the printer is not the problem. The page being sent is blank, or nearly so.

What to check, in order

  1. Print a test page from the printer's own controls. Everything depends on this.
  2. If it prints fine, stop looking at the printer — check the document, the selected printer, and print preview.
  3. If it is blank, print a nozzle check and read which colours are missing.
  4. New cartridge? Take it out and confirm all tape, seals and strips are removed.
  5. Reseat every cartridge until it clicks, and wipe the contacts with the printer off.
  6. Run one cleaning cycle, then a nozzle check. Repeat once. Then stop.
  7. Leave it overnight and try again before concluding anything.
  8. Laser: rock the toner cartridge gently and reinstall. Check whether the blank page comes out warm.
  9. Third-party cartridges? Test with an original as a diagnostic.
  10. Still nothing after two days of attempts? The blockage is beyond self-cleaning, and the decision becomes a printhead, a cartridge, or a new printer.

Stopping it happening again

The short version

Print a test page from the printer's own buttons before anything else. If it is blank, the computer is irrelevant and the fault is inside the machine; if it prints, the printer is fine and the problem is the document, the driver or the selected printer. On inkjets the usual cause is dried nozzles from sitting unused — and the right response is two cleaning cycles and an overnight wait, not ten cycles in an hour, because each one consumes real ink. On a new cartridge, check the tape and seals: an unremoved toner sealing strip produces a perfect print cycle and a blank page. And run a nozzle check after each attempt rather than cleaning blindly, so you can see whether anything actually changed.
