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.

Flatbed scan resolution is an impressive 1200 x 1200 dpi for sharp and detailed scans while copy speeds are as fast as 21 cpm, and you can quickly check and change settings via the 2.7″ color touchscreen.

An E2 error occurs when the printer attempts to print a single-page or multi-page print job, and the paper length selected in the print settings does not match the length of the loaded paper.
Use HP Print and Scan Doctor (Windows)

Use HP Print and Scan Doctor on your Windows computer to help diagnose and fix printing and scanning issues. Make sure paper is loaded in the main tray, and then turn on the printer. Download HP Print and Scan Doctor, and then follow the prompts to install and open the tool.

Check the print job settings: From the application you are printing from, click File > Print, and then click Options, Printer Setup, or Preferences, or open the Paper Type/Quality or Media & Quality menu. Make sure the color, paper type, paper size, and quality settings are correct for your print job.
A standard resolution of 300 dpi is acceptable for most text-based documents, while 600 dpi or higher is better for detailed photo scans. Choose the appropriate file type: The file extension you choose can affect the final scan quality. For most scan jobs, PDF, JPEG, GIF, and PNG are acceptable file types.
From the Home screen on the printer control panel, scroll to select the Administration menu, and then select the Scan/Digital Send Settings. Select a scan category and then select the Default Job Options to configure the settings. Select the Output Quality setting, and then select an option.
Most laser printers today have a default resolution of 600 x 600 dpi, which is fine for everyday text printing. For sharper output when printing photographs or documents combining text, photos, and charts, a higher resolution, such as 1200 x 1200 dpi or 2400 x 600 dpi, is preferable.
Laser printers, unlike inkjet printers, do not use ink cartridges. Instead laser printers use toner cartridges, so be sure to purchase accordingly depending on your printer. Toner is a fine dye power that is melted onto the paper.
Laser printers don`t waste toner in the same way, and because they don`t gunk up like inkjets, they may last longer before needing to be replaced.
If your printer`s status displays “Printer in error state,” there may be a problem with the printer itself. Make sure the printer is turned on and connected to your PC by Wi-Fi or cable. Check it for low paper or ink, and be sure the cover isn`t open and the paper isn`t jammed.
Run Diagnose & Fix

Open the HP Smart app, and then open Diagnose & Fix. Windows: Click the Diagnose & Fix icon in the bottom left corner. macOS: Click your printer, click Printers in the top menu bar, and then click Diagnose & Fix.

An Er/02 error message indicates that the toner cartridge door is open or not closed completely. To resolve the error, open the toner cartridge door, and then close it completely.
Quick fix. Error code e02 occurs due to overheating of the printhead or when the paper is not correctly placed into the input tray and therefore the paper feed rollers are unable to pick up the paper from the paper tray.
