Query: A Caveat for the HP 6940 Printer

A caveat for inserting a print cartridge into the inkjet printer...make sure the printer is turned on before you lift the cover. This allows the little plate in front of the cartridge receptacles to descend...otherwise this plate interferes with the cartridge insertion. I learned the hard way...I tried to insert new cartridges with the printer turned off; hence, the plate did not descend...and I forced it. In the process, I damaged the folding, wire spring that contacts the cartridge to complete the electrical circut...rendering the printer useless in part or whole.This is an excellent inkjet printer...the mea culpa aspects aside...I've just ordered another HP 6940 Inkjet Printer from Amazon. I recommend this printer to any one...but be careful.
