How to Identify and Fix Common Problems ?

Check inside the printer for any debris that might be causing paper jams. Turn off the printer, and then unplug the power cord from the electrical outlet. Remove any paper from the input tray. Open the rear access door, and then clean the paper feed rollers with a lint-free cloth lightly moistened with filtered water.
It is caused by an HP printer option called Mopier Mode being enabled by default. This mode causes only 1 copy to be sent to the printer which should then use its internal memory to print the multiple copies. If there is no suitable internal memory only the 1 sent copy gets printed.
Press and hold button for 15 seconds

Reset the HP 1200w Accessory to its factory default settings.

A piece of paper stuck in the paper tray or inside the printer can create a paper jam. Paper jams can occur for a variety of reasons, such as overloading the paper tray, loading different thicknesses of paper in the tray, or using paper that isn`t appropriate for your particular printer.
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.
Dust, paper fiber, and other debris might accumulate on the pick rollers and cause paper feed issues. To help prevent paper feed issues, clean the rollers inside the printer and in the duplexer (if equipped). If the other steps in this document fail to resolve the issue, then reset the printer.
You can continue to print with one or more empty cartridges, but HP recommends replacing them as soon as possible to avoid printhead damage.
On your PC search control panel, open control panel, Select printer properties, Select the “number of copies” it must be set to 2 change it to 1 and check if it helps. If the issue still persists uninstall the printer software from your PC and install the latest printer drivers.
Restoring the factory-set defaults returns most of the settings to the factory defaults. It will not reset the page count, tray size, or language.
Overfilling the paper tray is frequently causes paper jams. Many printers have sliding mechanisms that allow different types and sizes of paper to be fed into the printer. If the slider is not correctly positioned, it can cause a paper jam. Use standard office paper.
A piece of paper stuck in the paper tray or inside the printer can create a paper jam. Paper jams can occur for a variety of reasons, such as overloading the paper tray, loading different thicknesses of paper in the tray, or using paper that isn`t appropriate for your particular printer.
Some of the most common printer problems that most of us have experienced include paper jamming, slow printing, uneven printing, and wrong colour output. If you use your printer frequently, we know how annoying it can be to have persisting problems with the printer.
Try removing all of the printer`s ink cartridges and replacing them. Print out a few test pages to see if the issue has been resolved. If you are still experiencing skipped lines, try to remove the ink cartridge and replace it with a brand-new cartridge, as this can sometimes alleviate concerns.
A printer printing lines on the page are normally caused by a blocked, dirty, or damaged print head. Blocked ink cartridge nozzles, or not removing protective seals correctly when you installed a new ink cartridge can also cause missing lines of print.
The photo tray is overloaded. The paper is curled. The print side, or shiny side, of the paper is not loaded in the tray face down. The paper width guide is too tight against the paper stack.
If roll paper does not feed, cut the end straight across and uncurl it by rolling it backward, if necessary. Then reload the paper. If thick media does not feed, make sure you are loading it straight into the product, not at an angle. If paper jams when you print on both sides of the paper, try loading fewer sheets.
For cleaning, HP recommends using HP Equipment Cleaning Wipes, but you can use an HP-approved lint-free wipe and deionized or distilled water. Note: If dark spots appear on back side of prints, clean drum screen. Note: If minilab prints more than 2000 prints each day, clean drum screen up to twice daily.
What`s happening is that the drum or rollers could have a fingerprint or dirt that is smudging the toner on the page as it passes through to the fuser. It is normally caused by the rollers. If the marks are always in different places, then it`s most likely to be the drum.
Color Laser Printer or Black & White Laser Printer

As print quality goes down over time, this will be a reason to replace the color printer. We find a black and white printer can sometimes last 10 years or more and most color laser printers are replaced every 3 to 5 years.

Inkjet printers typically run at a lower price point than laser printers, and printer ink is cheaper than toner. However, laser printers and toner have a longer lifespan despite their high cost. Meaning laser toner cartridges have a lower cost per printed page than printer ink.
The quick answer is: Yes, you can (if you own a printer model that allows it) — but you shouldn`t keep printing with an empty cartridge for too long. Why? Because running on an empty cartridge for too long can cause your printhead to overheat resulting in irreversible printer damage.
When color ink is expended and black ink still remains, you can continue printing for a short time using only black ink. However, you should replace the expended ink cartridge(s) as soon as possible.
Doubling is a register problem that mainly occurs between plate and blanket within the unit. Too much blanket to paper pressure. Reduce printing pressure to a minimum. Too much plate to blanket pressure.
This is related to a printer driver setting known as the mopier mode. When the mopier mode is enabled, a printer can receive one copy of a document, and print multiple collated copies. The number of copies required is specified via a PJL header tag in the spool file.

HP Laserjet 2200, Tray 2 Pickup Problem, Gears Clicking
ANSWER : Definitely not a solenoid problem. I’ve worked on tens of thousands of printers and never replaced a single solenoid. You probably knocked something loose when you installed the pickup roller. Maybe something to do with the gear on the end of the pickup roller shaft. You’ll need to take the gear assembly off to be able to see it.

HP Laserjet 6MP wont feed paper
ANSWER : I had a similar paper pickup problem on laserjet 6mp. The printer would go through start-up sequence fine but when it received a print job you could here the main gears/rollers turning but no clicking from paper pickup solenoid, then eventually error lights would come one . I incorrectly assumed it was an error with the paper pickup mechanism and wasted a whole day taking the printer apart and replacing the paper pick mechanism. Long story short, if I had bothered to figure out the secondary error light codes from the start, I would have realized it was just a bad fuser and would not have wasted so much time.
