You are working as a technician at Certkiller .com. A user has asked that you check out his ink jet
printer. The printer prints text correctly, but there is a horizontal line missing in the middle of each
letter. Which of the following should you check FIRST?

A.
you should check the cable between the printer and the computer

B.
you should check the paper feed mechanism

C.
you should check the print head

D.
you should check the device driver software

Explanation:
The ink jet print head uses small holes to spray small dots of color on the paper. Sometime parts
of the print head clogs or dries out so that it is unable to print to a specific part of the letter and
therefore creating white lines through all the text.
