Question about HP OfficeJet K80 All-In-One InkJet Printer
This is an internal problem in the printer, there is a transparent tape in the printer and it needs cleaning or replaced

Here's the deal with the cartridge alignment page....the machine will
spit out a series of black lines mixed with yellow ink and at the
beginning of each of these lines is a "Green" check mark. The carriage
moves back and forth over these lines and green check marks and reads
them by use of what is called a "spot sensor" that resides on the right
side of the carriage assembly. This is usually noticed by the blue ray
of light that shines out of it. So if you are getting an alignment
failure one of two things is happening....1)You've have got a bad
cartridge (usually the color) and it is not laying down the right
colors, specifically the green check mark or 2)You've got a bad spot
sensor...even though it may still be shining the blue light, the sensor
board can't process the information. Its an easy fix either way.
