printer printing blank pages

 

toner-based laser/led printers

it could be

  1. toner (try replacing this first, cheapest solution)
  2. image drum (if you have been through about 3-5 boxes of paper or more). expensive
  3. laser (if printer is really old, greater than 10-20 years)
  4. check tech support on internet for your printer model
  5. bad printer. get a new printer.

inkjet printer

it could be

  1. bad ink cartridge(s) - it happens - bad chip?. replace with new cartridges.
  2. ink cartridge dried out. you have a problem if your heads are separate. if you can get at the heads, I usually use a clean finger with water to rejuvinate the print head, or just water first. if any water gets on the print cartridge contacts, dry those off, but don't attempt to dry the head off - there are little tiny holes there and material will get clogged in the jets and you don't want that.
  3. print head(s) - replace print heads (if your printer has separate heads and they are removable)
  4. wet or dry water/fluid/ink on cartridge's electrical contacts - use a damp/dry paper towel. damp side to wipe off the contacts (do NOT touch the head), then dry off copntacts with dry side. If you dare mess with the printer's contacts, make sure the printer is UNPLUGGED.
  5. check tech support on internet for your printer model
  6. bad printer. get a new printer.

some older printers you could not get the cartridge out if the cartridge wasn't empty. awful. had one very old inkjet printer like that, couldn't get the cartridge out, couldn't take the printer apart. it was a throw-away printer.

the printer will not print unless all the print cartridges are in.

dot matrix printer

problems you can run into

  • temporary fading as head heats up from overuse (solve this problem by letting the printer cool down until print head is touchable or even cool to touch - can take up to an hour)
  • fading as ink gets dry or used up (solve this problem by getting new ink cartridge)
  • tearing if triplicate too thick or printhead gets too old
  • fading as printhead gets too old (loses magnetic field capabilities like any solenoid)

I am going by memory, but if I remember right, printheads last for several years.

I used to use a fan on the printhead on long jobs to keep it cool. it helped a little. the head got really hot.

thermal printer

problems you can run into

  • won't feed at all
  • weak feed/paper slips on feed mechanism due to age or dust
  • blank printing - need to replace print head
