Inkjet “efficiency”

Sunday, August 19th, 2007

The “efficiency” of an inkjet printer is the proportion of ink that gets onto the paper. This depends on the detail design of the printer. Printers with separate ink tanks are known to use much more ink than those which have combined ink/print head cartridges, as in the former the head ...

Edible Printing

Sunday, August 19th, 2007

Yes, you can print on edible paper using edible colour inks in an inkjet printer, and then stick the paper on your cakes and such. You can't re-use the printer for ordinary printing, as you mustn't mix the edible and non-edible inks, for obvious reasons. The edible ink is a ...

Ink absorber full/waste ink tank full

Sunday, August 19th, 2007

This message comes up in two steps with Canon bubblejet printers. First there is a warning, then the printer refuses to work at all. What has happened is that the software has determined that sufficient head cleaning/purging has taken place to fill the waste ink absorber with waste ink. [It also means ...

Print Quality

Sunday, August 19th, 2007

Print quality: There is more to getting good quality prints than putting some ink cartridges in the printer and grabbing a handful of paper. This is particularly important when printing photos. Manufacturers recommend that you use their original ink, that you use their brand of paper, or other recommended paper, and ...

How can I save money on bubble-jet printing?

Sunday, August 19th, 2007

Unfortunately, the first answer that comes to most user's minds is "buy some cheap third-party inks". I'd like to explain why this is not such a good idea. While bubble-jets are 1) remarkably cheap, and 2) as good at printing photos as any other kind of printer at any price, they are ...

I swapped the printer but the replacement doesn’t work either

Sunday, August 19th, 2007

Various reasons for this, most of which you can work out yourself. (i.e. the printers aren't the problem). Hovever for the most interesting one we have to thank a most irate customer. He swapped a USB-connected printer for another one just back from repair and was most annoyed when it didn't ...

Do I need a printer driver?

Sunday, August 19th, 2007

The short answer is "yes" (For the non-expert, a driver is a piece of software that connects together your computer's programs and your printer.) Bubblejet printers are particularly fussy, as they won't work at all without a driver, and they won't work properly (or at all) without the driver for ...

Head Cleaning

Sunday, August 19th, 2007

Head cleaning is performed automatically by a bubble jet printer (and it consumes significant amounts of ink.) It can also be triggered manually from the printer driver software and utilities (typically). If that doesn't work, you can try removing the print head and standing the nozzles in a puddle of ...

How does the ink level gauge work?

Sunday, August 19th, 2007

Many printers will indicate the ink level remaining in the ink tanks, usually in the form of a readout on the screen of the associated computer. It will be a surprise to many users to be told that the printer doesn't measure the ink level. The readout is the result of ...

Poor print quality

Sunday, August 19th, 2007

This means that the paper feeds and printing action occurs, but the print is bad or even blank. Possible causes: Ink or toner tank empty Print head partly blocked. Print head electrically defective. Fault on print carriage loom (service fault) logic board damaged (service fault). Any combination of the above. If you think you have an electrically defective ...
