    Are you using the right screwdriver?

    I always wondered what the dot in the corner of the phillips head screws in Ricoh machines meant. I did some research on it and found that the dot denotes a JIS screw.



    Using a normal phillips head driver on a JIS screw will strip the head. Some brands of tools are worse than others. At our company we've found that a #2 phillips drywall bit works better than a regular phillips. It seems to be due to the grooves machined into the angles of the head which grip better.

    You may have trouble finding a JIS screwdriver. Moody tools is the only English language site that I have found that advertises their screwdrivers as specifically designed for JIS. There are many RC hobby websites that say that they sell JIS drivers, but these seem to be found as compatible by trial and error, in which case a drywall bit seems to be just as good.

    You might say this can all be avoided by using a 5.5mm socket, but there are screws, especially on fusers, that this won't work for. Also finding a 5.5mm socket on a 1/4 hex shank for power drivers is well nigh impossible.

    Anyone else have experience with JIS screwdrivers, or know a high quality site that sells a specifically JIS bit?

    Plain old #P2 tip works great as a sub.
    Don't take that toner with me!

    I don't think I've seen any #p2 bits at my local sears. Does the P stand for precision?

    The worst problem I've had was a Pro 906EX fuser where a bronze screw melted like butter as soon as I turned it.

    I never noticed the dots on the screws, but I have known the screws were different than 'Merican phillips head. I remember when the service manager told me that and I thought he was joking until he showed me the screws and drivers side by side. I kinda assumed everyone knew about it since I knew.

    We always used to use a driver instead of a phillips. You don't strip anything that way and the stubborn ones are a lot easier.

    That looks more like a Grayhound (Vodka + Grapefruit) but it should work fine for most field work.

    A guy I worked with loved using Wiha brand screwdrivers. I found that for the toner cartridges I work on, the Ames soft grip DIN screwdrivers fit their screws comfortably. Ames Supply also sells their green handle JIS drivers.

    For all of my field work, I use only Snap On screwdrivers, as there is no play in the screw head and they work great. For the Ricoh boxes and other manufacturers that they work on, the 5.5 mm drivers come in very handy.
