How often do you replace the grids, charge wires and developer. I have a few of these with 450k or close to it and the only thing I've done is replace the web. I have a pm kit but I'm wondering how long they can be stretched.

Every 300k, according to the manual, but some parts like the hot roller easily exceeds 500k. -
Good question. But you should understand that there are 2 things - recommended PMs and real life. To ask question like this you should always clarify what exactly are you looking for - manufacturer's recommended numbers or actual life experience. Hot rollers can run way more that 500K copies, developer can run much less than 300K etc. It's all depend on different conditions (coverage, humidity level, room size, ventilation etc. I can continue on and on).
Personally , I replace grid and wire when it's getting "rusted" - look on an agle to the sun light and if you see a grid covered with an orange/brown color buildup - it's time for sure. Once replacing grid replace a wire too.Comment

We run devs and dev filter to 600k. Grid, wire, drum blade, brush and filter at 300k. Drum at 1m. Dev unit bushings at 1.2m. Registration mylars at 1m. Everything else is more or less fit on fail.It's 106 miles to Chicago. We've got a full tank of gas, half a pack of cigarettes, it's dark and we're wearing sunglasses.
Hit it.Comment

not so much worried about manufacture, thats all in the service guide. I was just curious what other techs are doing. I have been told that the dev. unit will start making a mess in the machine if u let it go to long. which is understandable. we have some 1356's that went to nearly 1.5 mil before we ever did dev changes. and a transfer belt tht went over 2mil but we paid for that. it stuck to the silver roller and started giving us problems until we noticed what was happening. thanks for the info..Comment

Most of our DV's don't last past 600k here in Texas. The Coronas can last over a mill. Drums 500K or so. Brush Ruller at same time as drum. They seem to go bad often enough we have to vac the drums a lot cause the mylar gets too much toner build up and causes streaking.Comment

See attached excerpt from the Service Guidelines.
I would stretch the 300 K PM to 400k, but fit the Dev and Transfer parts at the same time. This should average out the costs, cut down return visits for individual parts and match up with the Drum service interval (1.2M). We have had Dev seals fail at 600k (!) on a new machine so it may be worth changing these while the dev is being done. MUCH cheaper than rebuilding the feed stations!Comment
