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.
If the error message, Unknown device appears, this can indicate that there is not adequate power and the PC can not identify the printer correctly. Verify that there are no extension cables and that the power cable is no longer than five meters. Reseat the power cables.
Select Start, type Control Panel, and then press Enter. In Control Panel, select the View Devices and Printers item. Select Add Printer at the top of the window. After the wizard started, select The printer that I want isn`t listed.
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.
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.
Ghost prints happen when the drum or fuser unit within your printer become faulty. Because a fault with this element won`t heat the particles of the toner to a high enough temperature, the marks being made on the paper are much lighter in colour and appear more faded than typical documents.
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.
If you see an “unknown accessory detected near you” message (or similar), it means there`s an item compatible with the Find My network that might be traveling with you. If so, its owner may be able to see your location. You should look to see if something you`re borrowing has such a device attached.

If you`re using Windows 10, click or tap the “+ Add a printer or scanner” button.

The easiest way to connect the Canon printer to the computer is via a USB cable. It`s the traditional method of connecting devices. One end of the USB remains connected to the printer, and the other must be connected to the computer`s USB port.

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.

The problem of the printer icon not displaying in devices & Printers is frequently resolved by downloading and installing the most recent printer driver. If your printer drivers are out of sync, they may not function until you download and install the latest update.

Need help for cleaning epson r300, have a kit
ANSWER : Don’t worry about the paper towel. Keep the heads as far to the right as you can and the fluid will just go into the waste sponge underneath. There’s nothing you can damage with the fluid. I wouldn’t worry about the pad that got torn. Just insert the syringe in the nozzle and gently push the fluid down into the heads. This site sold tens of thousands of those kits and I guess the instructions were pretty good because there was never a single complaint.

Need help
ANSWER : I usually look for screws that might be holding it. If it doesn’t come off after removing the screws, sometimes you have to slide it to remove it. If that doesn’t work, then you get out the small, flat bladed pocket screwdriver. Use it to gently pry around the edges of the panel. Have you tried grabbing the paper clip with some needle nosed pliers? Either that or a small magnet to pull it out. Another possibility would be to hook the clip and pull it out that way.

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.
