|Can't help with scanner, but when the printer goes through all the correct motions with no error messages, but noting is printed, it usually means a severe ink-blockage of all colours inside the printer.|
The blockage is caused by ink drying up because it hasn't been used for a while.
Remove all the cartridges and put a few drops of alcohol-based solvent in each hole where the cartridges sit. Leave overnight. Replace cartridges the next day and run the cleaning cycle a few times in the printer driver.
