No need for a tech to install it. Just grab the file from here and run it.
If it doesn't completely resolve it, you may need to do an Altboot or an Erase Customer Data.
But there is no point in going down those roads unless you confirm the update itself doesn't work to fix it.
It is possible to be a software bug and you will need a tech to install latest SPAR firmware 100.xxx.038.10200.
Wondering if anyone else has an issue with the C8045 printing THREE (always 3) striped pages during the middle of jobs that are run through the Bypass Tray. It can occur randomly, but usually happens in the middle of job that requires the Bypass tray to be reloaded with paper. This happens at least 4 or 5 times a week for us. From what I have noticed, it also seems to often occur if you reload paper and don't confirm the paper type in time before it starts continuing the print job. It has been doing this for about 5 months now. Doesn't matter if it is a 5x7 postcard or an 11x17 tabloid size sheet or envelopes. Example attached. Sometimes the printouts are just yellow stripes, sometimes a combo of Cyan, Magenta, or Yellow. But again, always occurs in Threes.
Also if it does occur in a print job of let's say 50 prints, it will use 53 pages of paper. It is not replacing three prints ith these stripes. And while it appears as a crazy bug, it is frustraying when we are printing on paper that we have a limited number of and each print matters.
