HP 1315 printer won't turn on

SOURCE: What paper jam?

Does the printer even try to pick a piece of paper from the supply tray? If not, then it would appear that a sensor somewhere in the paper path is bad, either mechanically or electronically. Often, these sensors have a lever which touches the paper. If by chance the lever is broken or stuck it won't give a correct message to the logic circuit. If by chance the sensor is electronically defective, it would still give a bad message to the logic, and it would need to be replaced. Logic circuitry could be bad, in which case, replace the printer. With the lowcost printer/all-in-one units these days, it seems fixya has a continual flow of inquiries. Maybe this will give you some help.
