SHARP AR-287 F2-00 error code

Machine does not reintialize and is stuck on F2-00 (toner control sensor open)
Machine called for more toner and has been refilled.
Used reinisitalize codes "14" and "16" to restart, but goes back to F2-00.
What else can we try?

Although this appears to be an ATC (automatic toner control) problem and it may list as such in service manual which gives brief description of error code it is often something else.
There is a sponge roller at bottom of toner that wears down considerably and when the hopper is very low or out of toner the otner light will come on(triangle of dots). The customer puts the new toner in and the sudden surge of a large amount of toner cascading into the hopper causes an excessive amount of toner to go past the sponge roller and directly into the developer unit which is directly under toner hopper.
The ATC sensor is on the bottom of developing unit and "reads" the density of the developer /toner ratio and with a very overtoned situation as the one created above you would get an F2-00 code.
What is normally done is to either dump toner out of hopper and replace sponge roller and seals or replace toner hoppers as a whole which is quicker and costs almost rh same as cahnging the sponge roller and seals is more labor intensive.
Also the developer is now contaminated with an excessive amount of toner and the recommende solutin is to replace the developer and calibrate theu service program.
This is hardley recommended by a service man unfamiliar with this mode let alone the customer. I ahve been in the Bay Ridge area for years and as a matter of fact bought an investment property thru Petses Realty. Frank

This means that the cartridge's sensor is miscommunicating with the copier memory thus the code U2 -40.

Perform this code ;# , interrupt , C, Interrupt keys in that order and press 16 then Print key and the code will be cleared.

H4 for an error code on all Sharps indicates that the fusing temperature isn't correct. It needs to have a new thermistor installed or the heating lamps need to be replaced.
