Check Cables and Printer USB Ports

Check all cable connections (including the power cord) on the printer side. If the printer does have power and you`ve properly connected the communication cable, but the printer is still not recognized, try switching to a different USB port on the PC.

Primary causes include grime, dust, worn rollers, or incorrect paper weight.
Make sure that both ends of the USB cable are correctly inserted into the computer and the printer. Try disconnecting and reconnecting the USB cable at both ends. Disconnect the printer and the computer and reconnect them. Try another USB port if available.
Open the start menu and select Control Panel > Administrative Tools > and choose the Services icon. Locate the Print Spooler service and right-click. Then select the option to “Stop” the service.
Usually a quick paper setting adjustment will clear up a ghosting issue right away. Run a cleaning – Most printers have a cleaning function built into the machine. Run this a couple of times to attempt to clear up the printing issue. Inspect the drum – Sometimes excess toner powder can stick to the drum.
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.
1. Paper Jams. Paper jams are a common problem for printers, resulting in time-consuming and frustrating delays. It can occur when loose sheets of paper get stuck in the rollers or feeding mechanism of the printer.
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.
Restart devices

If your printer connects to a Wi-Fi network, disconnect your computer or mobile device from the network name (SSID), and then reconnect it to the same network name your printer is connected to. If the printer is available and has a ready status, the issue is resolved.

The Print Spooler is software built into the Windows operating system that temporarily stores print jobs in the computer`s memory until the printer is ready to print them. In some circumstances you may need to stop and/or restart the service.
Click on Device Manager from the context menu. In Device Manager, click on View and select Show hidden devices. Next, expand the Printers section to view your printer.
Ghost printers are printers that continue to appear in Windows although they have not been used or installed on your system in a long time, which may have been years.
Shadow printing is a printing technique that creates a lighter shade of the text off centered to make the text appear to have a shadow beneath it.
During the printing process, paper, toner and dust particles can accumulate inside the printer. Over time, this buildup can cause print-quality problems such as toner specks or smearing. This printer has a cleaning mode that can correct and prevent these types of problems.
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.

1. On the printer display home screen, select the “set up” button (it looks like a gear). 2. Select “settings” > “device settings” > “reset settings” > “reset all” > “OK” and then “Yes.”
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.
Simply plug the USB cable from your printer into an available USB port on your PC, and turn the printer on. On the taskbar, select the Search icon, type Printers in the search bar, and then select Printers & scanners from the search results to open the Printers & scanners system setting.
In computing, an error code (or a return code) is a numeric or alphanumeric code that indicates the nature of an error and, when possible, why it occurred.
Simply plug the USB cable from your printer into an available USB port on your PC, and turn the printer on. On the taskbar, select the Search icon, type Printers in the search bar, and then select Printers & scanners from the search results to open the Printers & scanners system setting.
If you`re using Windows 10, click or tap the “+ Add a printer or scanner” button. No matter if you`re using Windows 11 or Windows 10, the operating system begins “searching for printers and scanners,” and if it manages to find your local printer or scanner, it will try to install its drivers automatically.

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.
