- Clear the queue: stop/delete print jobs and print a test page.
- Check consumables: cartridge/toner fully seated, protective film removed, contacts clean.
- Check the paper path: paper loaded correctly, no scraps in the feed, rollers not dirty.

FAQ
Why won’t my printer recognize a new cartridge?
Common reasons: protective film not removed, cartridge not seated correctly, dirty contacts/chip, or firmware/series variants blocking recognition. Start with the recognition guide.
What to do with a paper jam when you can’t see anything?
Check the entire paper path (rear/service flap), clean feed rollers, and use the correct paper format. Often a small fragment is stuck in the feed or at the duplex unit.
The printer is online but won’t print — why?
Often the queue is stuck, the wrong printer is selected, the driver is broken, or the port is incorrect. A test print + driver check resolves many cases.
After a firmware update, cartridges are blocked — what can I do?
Depending on the manufacturer, reset steps, re-pairing, rebuilding Wi-Fi, or firmware strategies can help. First check whether the issue started right after an update.
Why is my printer printing streaks or smudges?
For ink printers, nozzles/venting/contamination are common causes; for laser printers, it’s often the drum, toner, transfer roller, or fuser. The article helps you identify the pattern correctly.
Once you’ve identified the problem: enter your printer model or cartridge number in the finder — you’ll find matching products and avoid wrong purchases.
