How to Identify and Fix Common Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

Paper Feed Gear Problem: The paper feed gear is responsible for feeding the paper into the printer. If there is a problem with this gear, it can cause the carriage to jam. Cartridge Carriage Stalled: If the cartridge carriage is stalled, it can cause the printer`s carriage to become stuck.
If your printer won`t print, a print job has stopped unexpectedly, or you received a “carriage jam” error, your printer carriage is likely jammed. These jams occur when the carriage holding the ink cartridges stalls in the printer. Carriage jams sometimes occur after a paper jam.
Dust, paper fiber, and other debris might accumulate on the paper feed rollers and cause paper jams and paper feed issues. Clean the rollers inside the printer, and then try to print again.
Most commonly “Cartridge Problem” means that your HP printer simply cannot recognise the colour or black ink cartridges. Thankfully however this error message can usually be cleared with some basic troubleshooting.
Get a flat something to use as a pry bar. I would suggest the back of a spoon handle, or a dull table knife. Insert the pry bar between the top of the cartridge and the underside of the carriage slot. Slide it forward and then gently lift the pry bar slightly, just enough to allow the cartridge to be pulled free.
Low-quality paper leaves an accumulation of tiny paper bits often referred to as “paper dust” inside the machine. This “dust” is one of the top causes of paper jams. More dust means more jams. Besides jams, the dust also contributes to poor-quality prints and causes machine parts to wear at a faster rate.
A paper jam is when paper or other printed material gets stuck or lodged in a printer and cannot eject.
Sometimes a paper jam error persists even though there is no jammed paper (false paper jam). Reset the printer, which might clear a false paper jam error, and then try to print again. With the printer turned on, disconnect the power cord from the printer. Unplug the power cord from the power source.
Missing colours, streaky prints, smudges and ink blotches are all signs that your printer ink or toner cartridge may be damaged. Some printers will actually warn you if a cartridge is damaged and will refuse to print. This includes HP ink cartridges, Samsung toner cartridges and Canon ink cartridges.
Fix this problem by removing the cartridge and injecting more ink into the sponge through the exit hole. Air bubbles also can get trapped inside the cartridge, blocking ink flow. Allow the cartridge to sit unused for about an hour to give the bubble a chance to dislodge by itself.
Low-quality cartridges or improperly stored cartridges can cause paper jams. For example, too much toner or ink can be released onto the paper, or the toner or ink can clump together in the cartridge.
