If the “Scanner error 2” keeps coming back, you should replace the flatbed scanner assembly. The “Scanner error 2” usually triggers when the scanner`s drive motor fails. Fortunately, replacing the flatbed scanner assembly is not considered difficult.
Right click on the printer and select Printer Properties. Click Print a Test Page. After the Test Page has printed, click OK.
1) Ensure printer`s power is OFF . 2) Press and hold the FEED button. 3) Power printer ON, only releasing the FEED button when printing begins. 4) Remove Self-Test page(s) after printing completes.
A printer test page is one of the easiest and most effective ways to analyze and calibrate your printer`s performance. Test pages often include text, graphics, and images that, when printed, aim to maintain the health of your printer (and cartridges) while highlighting any issues that your printer may be having.
Printing a test page helps you make sure that you don`t waste ink on your printer`s cleaning function. It also prevents damage from happening to more important papers you may need. When testing a page, print an image that uses a lot of color.
A printer test page is simply a test print that tests the quality of your printers and the number of colors being popped out through the printer head. Almost all new printers have the print quality check functionality that allows you to print a test page to scan for printer ink.
To calibrate the scanner

Go to the front panel and tap the Settings icon , then Scanner preferences > Calibrate scanner. Follow the instructions in the front panel.

On the printer control panel, touch the Wireless icon ( ), and then touch the Settings icon ( ). Touch Print Reports, and then touch Wireless Test Report. A Wireless Test Report prints.
Use the Windows built in scanner software instead of the software that came with your printer. You can access this by clicking “Start” then “Devices and Printers.” Then, you should be able to select the scanner icon, which launches the windows scanning utility. This will work regardless of ink status.
You will cover one eye, and then, using the uncovered eye, you`ll look at a series of test cards. Each card contains a multicolored dot pattern. There`s a number or symbol in each color pattern. If you can identify the number or symbol, you`ll tell the doctor.
You can check your color mode by going to File → Document Color Mode. Make sure there`s a check next to “CMYK Color.” If “RGB Color” is checked instead, then change it to CMYK.
Navigate to Window > Color > Color to bring up the Color panel if it is not already open. You will see colors measured in individual percentages of CMYK or RGB, depending on your document`s color mode.
In print, the user is able to physically view and feel the printed material, interacting with it directly. In web, the user views the content through a screen.
Doing a printer test page will uncover and pinpoint possible causes as to why the device stopped printing. It can identify a clogged printhead and alignment problem and help match color replication as well. By identifying an issue through this test, you can resolve the problem faster, preventing it from becoming worse.
The color block serves as a pattern interruption on your audience`s social media feed. The goal is for this square to “stop the scroll” of your ideal audience for long enough to have them read the words on your square. 3. We are going to use your 10 color blocks to test which pain points resonate with your audience.
Ctrl+F12 Opens a file.
Ctrl F2 Deselect all items on screen. Ctrl F3 Start/end of block. Select the first item; click the button.
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.
The HP Smart app is the main software for your printer. Install it on the device you want to print from, and then use it to set up the printer connection.
HP+ is a free upgrade available with many HP printers. It links your smart printer with smart ink and a smart app into a single cloud-connected system.
Printer calibration enables you to keep track of “device drift”. Over time, even with consistent use of the same consumables (ink, toner, paper), your printer will suffer from device drift. We calibrate to make the printer behave consistently and bring it back into a repeatable state.
On the control panel, open the Setup, Service, or Settings menu. Select Preferences, Printer Maintenance, or Tools. Select Web Services, Printer Update, or LaserJet Update. If prompted, follow the instructions to turn on Web Services.
Open the Windows Control Panel and navigate to Hardware and Sound | Devices and Printers. This screen will show you all of the printers that are installed. Right-click on the printer that is experiencing problems, and then select the Troubleshoot command from the shortcut menu.

My 2550n Color LaserJet does not want to print in color
ANSWER : That model had issues with the carousel solenoid sticking. That might explain why it works after you let it sit for 10 minutes. The solenoid gets hotter with use which causes the deteriorated foam on it to become sticky and hold down the release plate instead of letting it go. This allows the carousel to spin when it is supposed to stop for each color. The solenoid is located on the right side of the printer. If you open the lid, it is just behind the opening at the top right. You need to remove the top of the printer and scrape off the goo on top of the solenoid body. I put a piece of thin sticky backed felt to replace it. Other people use electrical tape.
