Thraser, your still battling this machine? Of course your readings will be off if you only have developer coverage over half the mag roller? That's where I would start. I also now wonder about your model #, because I don't think that the 450 has a VSDP reading, but the newer ones do. It refers to the "immediate post-pattern output" of the ID sensor -not surprised that these readings would be whacked!

Description: One of the following ID sensor output voltages was detected twice consecutively when checking the ID sensor pattern. 1) Vsp ? 2.5V 2) Vsg ? 2.5V 3) Vsp = 0V 4) Vsg = 0V
Possible Problems: • ID sensor defective • ID sensor connector defective • Poor ID sensor connector connection • I/O board (IOB) defective • High voltage supply board defective • ID sensor dirty • Defect at ID sensor pattern writing area of the drum
** Generally, I've found this problem to almost always be one of the last two items listed above.
This code can be reset be turning off the main power (orange rocker switch) for about 10-seconds and then turning the machine back on. If the error comes back up, then there is a definite problem with the machine and it should be looked at by a train service technician.

Remove PCU, remove development unit, remove cover (2 plastic C-clips) remove filter, remove development roller (2 shoulder bolts). Clean roller and empty all developer. Pour in new developer, re-assemble unit. Reinstall drum and Development unit. Place a small piece of paper between the PCU and toner entrance hole to prevent used toner from entering dev. unit during calibration. Perform SP2-801. Remove paper form dev. unit
Hello sir; Just follow the steps;
1, dump entire dv use vaccunm cleaner to cleanup don't leave any dv inside.
2, thorughly clean out magnet roller by rubbing alcohal.
3, pour in new dv evenly.
4.Do simulation 2801 & 2805, the procedure as follow;
press"clear mode", "107", press and hold "clear/stop" key for 3 seconds, then press 1 for copier sp then enter2801 press start, after that go to 2805. same procedure. Let me know the resolve.
You're talking about two really old machines, the 450 from 1998 & the 7025 from 2000. Both are about the same class, but I'd give the edge to Ricoh since it was also sold under a number of other brands & replacement parts are readily available. Hope this helps...
