Our shop is weird... which is why I cant fault HP for it. I hate their obscure codes that could mean anything is broken... but I dont blame their machines for actually breaking down.
Last year we had 16 power outages in the span of 2 months. The year before that the same. They did a bunch of upgrades in our area... and this year so far it's been 2 in summer. Our FB500 had a PSU die and motherboard die because of it, our graphtec also had the main board die after an outage... So it's hard to blame the machine when every machine we have started to have issues.
We were told its not the surges that kill these machines, it's the sudden drop in electricity that does, so surge protectors wont help in our case...had to get a huge UPS. It'll work all of 3 minutes while the machine is running before it ends out of juice... but thats enough to cancel a job and turn the power off ourselves. Our flatbed hasn't had issues since we got it a UPS... The latex is more power hungry and we paid around 2K per latex machine to get a UPS... so we just bought it last week, we'll see if it helps with our latex's phantom errors!
And yes. I started with a 110 at home because our old owner wouldnt touch latex printers... I wanted one to play with. They loved the quality of it and bought a 560 a month after I got my latex... then a second one... then a 360 for traffic. Then I saw a forclosure auction selling a 560 for $7000... jumped on it, sold my 110 for $5000 and never looked back. I love the 560s loading mechanism and the machine itself... I know having one in my home is overkill, I do sell a few things online and it's paid for the machine 5x over... not bad as a second income! It's great to have when our work machine is down as well. Right now we're down to 1 560 and 1 360 (We traded one 560 for a 360 so we can do traffic) I hate using the 360 because of the loading mechanism... and the 560's heating fans throw an error after every print. So I have to reboot the machine every single print... It's not too bad, but currently we have 15 different medias to print on (I saved all the small misc material jobs for last). I tried... and just couldnt do it. Loaded the truck up with all the rolls...went home and printed it all at home. So it may be overkill, but it's saved our butts a few times!
Of course having a 560 / laminator /graphtec at home kind of sucks when we have a rush job, and get asked to bring a bunch of stuff home to print for next day delivery... but worth it since I get a 560, great machine.
