If a printer is out of paper (the hoppers are empty and there no packages of new paper to be found near the printer), then a fresh package or box of paper can be fetched from the mail room. Before you take some paper, please notify the Font Desk Receptionist so that the inventory can be kept up to date. If possible, please take an entire box so that this tiresome exercise need not be repeated often.
If the printer reports in the LCD window that it is low on toner, then what to do depends on how fresh this message is. The toner sensor is very conservative and will report "Low Toner" even though there is plenty of life left. To ascertain whether the toner is really running out, print a test page. If the printout is getting very light or has bald patches, then open the printer, shake the toner cartridge, reinsert the cartridge and print a few test pages again. If it comes out spotty again, then it's time to change ther printer cartridge.
Contact the IT staff to replace the cartridge.
