How to Identify and Fix Common Problems ?

The printer is either low in toner, the density is set too low, or the Economode may be turned on. Remove the toner cartridge and shake it. This will redistribute the toner and often will temporarily solve the problem. However, this usually indicates it is time to install a new cartridge.
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.
Most printers will stop working when they`re out of paper, ink or toner, or if the unit detects an issue with the ink or toner cartridge. When this occurs, you might receive an error message or notice blinking green or amber lights on your printer.
During a print job, the ink cartridge carriage stalls in the printer, and a Carriage Jam or E3 error displays on the printer control panel.
Turn the product on while you press and hold the Resume button for 10-20 seconds. The Attention light turns on. Release the Resume button. The Attention and Ready lights cycle while the product restores factory defaults.
If you are having trouble getting your cartridge to read properly or are having connectivity issues with your printer, sometimes a hard reset will resolve the problem. Power down the printer and then unplug the power cord from the printer and the wall. Wait for a minute, then plug the printer back in.
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.
Among the more common technical issues that may bring down a printer are disconnected cables, malfunctioning routers, and low ink levels. Moreover, software problems such as interrupted connections or incorrect settings in your system`s drivers can also cause your printer to show up as offline.
The most common reason is an unreliable connection between the printer and the computer. You might also have a paper jam, out-of-date drivers or a print spooler service with bad data.
1: Check Printer Power, Cables, and Paper

Check that the correct paper is properly loaded into the printer and is not jammed. Replacing damaged cables, plugging in loose or disconnected cables, and fixing paper jams as necessary may resolve the issue.

Turn the printer off then back on. If the issue persists, turn the printer off, unplug the power cord and then wait at least three minutes before plugging the power cord back in and turning the printer back on. If the issue persists, ensure the product is running the latest firmware available from HP.com.
Make sure the printer is on and connected to your computer. Go to HP Software and Driver Downloads, and then enter your printer model. Select Firmware from the list of drivers, click Download next to the update, and then follow the instructions.
Reset. Resetting the printer stops printing and clears the current print job received from the active interface. You may want to reset the printer when there is a problem with the print job itself and the printer cannot print successfully.
Click Start . Press and hold the Shift key, click Power, and then select Restart while holding the Shift key. Continue holding the Shift key while the computer restarts.
Volatile memory requires power to store the information. Deleting volatile memory is easy: Simply shut down or unplug your printer for a minute or so. Most printers also have non-volatile memory (a hard drive) that is stored until you physically delete it.
Jam Recovery Mode runs the printer for a brief period of time to move the paper further into the exit tray. To run Jam Recovery Mode: Press and hold the [Clear All] button for three seconds. After the printer engine stops running, turn the power off, then remove the jammed paper.
Turn the printer off then back on. If the issue persists, turn the printer off, unplug the power cord and then wait at least three minutes before plugging the power cord back in and turning the printer back on.
One of the most common causes of paper jams is that the paper has simply not been loaded correctly into the printer paper feed. With this in mind, remove any paper from the tray in order to check for any jams. If you do see some paper jammed, pull each sheet out of the printer slowly until the printer is clear again.
The error message indicates that the printer is either turned off, not properly connected to your computer or missing an internet connection. Another possible reason for the general error state is that your HP printer is running low on paper or ink.
To remove printer and driver on Windows 10, open Settings > Printers & scanners, select the printer, and click “Remove device.” Then open Print management > Custom Filters > All Drivers, right-click the driver, and select “Delete.”
Select Start , then select Settings > Devices > Printers & scanners . Scroll down to Related Settings and select Print server properties. Select the Drivers tab, and see if your printer is listed. If it is, you`re all set.
Each printer has a preset maintenance interval, which occurs after a certain amount of pages are printed. The maintenance interval lets the user know that it`s time to install the maintenance kit so that the parts within the printer do not get overused.
Certain types of basic maintenance are simple enough that you can do it yourself. Things like changing the toner cartridge or refilling the paper do not require special knowledge. Just review your owner`s manual before you do it the first time and you`ll be all set.

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.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.
