Insert the stack of paper into the product, and then gently push the paper guides snugly against the paper. Make sure that the paper is fully inserted into the product. Try printing again. If the issue is not resolved, try loading different brands of paper and different types of paper, one type at a time.
Requirements: Operating System – Windows 7, Windows 8, Windows 8.1, Windows 10.
An Er/04, Er/05, or Er/06 error message indicates a paper jam. Find and clear the printer of any jammed paper, or reset the printer if the printer has no jammed paper.
Paper Overloading

Because many desktop inkjet printers are top-loading, it can be easy to overload the tray.

The most common cause of this issue is paper misalignment. Make sure you properly insert the papers in the tray and avoid overfilling the tray. If this doesn`t solve the problem, check the troubleshooting section of the printer`s user manual.
Click the Copy/Print or Print tab. Open the Manage Trays menu. Modify the tray settings.
The Error Code 6 means that there was an issue communicating with the Google Play app on the phone (various possible reasons). 1) Reboot the device and try the purchase again.
Remove the roller cover inside the printer. Pull up on the tabs, then slide the rollers to the left to remove them. Insert the replacement rollers and slide them to the right until they click into place. Replace the roller cover and press down on it until it clicks into place.
Lightly dampen a clean, lint-free cloth with bottled or distilled water, and then squeeze any excess liquid from the cloth. Press the cloth against the rollers and rotate them upwards with your fingers.
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.
Try moving the router and printer closer together.

Switching to a wired connection, then back to wireless, can sometimes work as well. Persistent print problems might be a sign that it`s time for a new machine.

A paper feed issue can occur for several reasons, such as dusty or contaminated paper rollers, the condition of the paper in the tray, or even issues with the software. To resolve the issue, try each solution in this document, and then use the steps in this section to print a self-test report.
The tray settings determine how the printer manages the paper trays.
Open the System Setup menu, and then open the Paper Setup menu. Select the tray that you want to configure. Select Paper Type, and then select the desired paper type for the tray. Select Paper Size, and then select the desired paper size for the tray.
Tray protection

This will be used to prevent like paper from being fed if Auto Switching is ON. Press Printer Setup > Tray Settings > Settings > Tray Protection. Choose a tray and press the button to activate this function.

Your printer should have been packaged with a USB cable regardless of whether it is a wireless or wired printer. Plug the cable into your printer and your computer`s USB port. The direct linking should trigger your computer to recognize the printer and start up the software needed to complete the installation.
Check cables or wireless connection

Make sure that the printer`s USB cable is properly connected from the printer to your PC. If your USB isn`t recognized, see Automatically diagnose and fix Windows USB problems. Check the wireless connection (for wireless printers).

Your ”Windows Cannot Connect to the Printer” error may result from outdated printer drivers. In this case, you can fix the issue by updating the installed drivers. Windows` Device Manager automates the process, so you don`t have to find and install the latest drivers manually.
Instead of adding the printer to the existing network, you may attempt to print via Wi-Fi Direct. In case this does not work as well and you refuse to use HP Smart, it`s on you to bring the right drivers and install them manually.
This error has the following causes and solutions: The result of an assignment, calculation, or data type conversion is too large to be represented within the range of values allowed for that type of variable. Assign the value to a variable of a type that can hold a larger range of values.
The Error code 6 can often appear if you`re using a proxy servic or a VPN service. If you are, quit it and try signing in. Additionally, check that no proxy service has been set up manually. Open the Settings app (Win+I keyboard shortcut).
This error code means your connection to the matchmaking service has timed out. Please try joining a match again. Should you continue to encounter this error after trying these steps, or if you have any other questions, please get in touch.
What does Exit Code 6 indicate? If the same deployment is working on other computers but failing on just the one computer, then it`s likely an issue with psexec not being able to properly/successfully run on that particular computer.
According to Canon, Error 06 indicates a fault of the sensor cleaning module.

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.
