I don't know what the numbers are, but the little abrasive cut-off wheels are held on with a mandrel type bit and a screw. Make sure you get the right size wheel and the right size mandrel, they make a couple different sizes, you can't fit the small wheels on the bigger screw. Anyway, I use my cut-off wheels all the time, usually to get stubborn screws out by cutting a slot in the head and turning it out with a flat blade screw driver. The wheels will cut anything, most people scoff when I say that, but it is true, they will cut anything.

Press the Shift/Mode key and set the Input/Output to MathIO.
Even that will not guarantee that the display will be in root form. Only square roots are possible.

Sharp AR-207... | Answered on May 24, 2020


First, be sure all four toner cartridges are seated properly as is the transfer belt. Close the front panel, then the top panel, power-cycle the printer and try again. If that doesn't solve the issue, it sounds as if either the actuator for the front door switch is broken off (which is highly unlikely) or the door switch itself is out of position. Getting to the switch involves removing most of the panels just to get to it; not impossible, just involved and a LOT of screws, plus a small black spacer for the top-left panel hinge. If you have any kind of a warranty or maintenance agreement on the printer, DO NOT TRY THIS, you WILL void it!! You have to unplug the printer, remove the fuser from up top, then the top panel, lower the front panel and remove the transfer belt and keep it out of the way in a dark area. Remove the hinged rear panel at the rear bottom followed by the rear panel (which fits inside a side panel, something to remember when reassembling). Now the side panel. If the switch is out of position, reposition it. If it's broken, it will need to be replaced. Reassembly is in the EXACT opposite of disassembly. You may wish to forego this and get an HP authorized tech in to do this for you. Worst Case Scenario: the DC Controller board is bad. But that's also unlikely ... possible, but unlikely. Let me know how it turns out!

Are you using genuine HP cartridges?
According to HP, the two cartridges for your printer are the 564 and the 564XL. Either cartridge will work.
HP does not offer another size.

Take the black one out that's in there now and see what the Part # is... then do a search for it.
