    Excellent resource. Two years since I attended training course, and due to sit exam later this week. Your videos have been invaluable to me in my “cramming” session. Thank you so much.

    nice simple explanation of a lazer printer. my last 2 printers have been inkjet printers. i have them both setup with bulk ink systems which drastically reduces the price of printing. maybe not on the exam, but is nice for your readers to know to pick an inkjet printer that has an bulk ink system available from 3rd party companies when picking a inkjet.

    Ive been studying the in’s and out of lazer printers on and off for months and the discription you use to describe the process along with the pictures as you go through the steps of how it works is really eye opening. The wiping clean of the drum first, the negative charge on the drum so that the lazer beam can draw its image into it and the ink is attracted to the parts which arnt nagatively charged anymore on the drum due to the lazer writting the image onto the negative charge…its a really good explaination.

    Your the top A+ teacher Mr Messor!
