Joe Churma - Printer Technician
A few weeks back, I ran into an unusual problem on a HP Color LaserJet 4700 getting streaks on its 8 1/2” x 11” forms. The streaks were from the yellow toner cartridge. The customer told me they were having the same problem on all of their cartridges in the past and they would replace them when they had this streaking problem. I asked the customer to show me all of the type forms they were running on the printer. The customer showed me a thick small card stock of 2 different sizes they used to print out birthday, wedding, holiday, and similar type cards for their business.
The customer was properly setting up their printers MFP Tray parameters. What I found was the card stock they were using had a slight bow in it which resulted in the left and right edges of the card stock forms scraping the image drums. I showed the customer how to work the bows out of the card stock forms. This will save the customer extra cost of going through toner cartridges, giving them a higher profit on their cards that they sell to their customers.
