Sharp AR-M277 reviews and thoughts anyone

[kingpd@businessprints.net]

Hey guys/gals,

I don't dabble in sharp too much but I have an opportunity for a bulk lot purchase of sharp ar-m277 machines. I know they're slightly older but are these a good model to place in the field or should I stay away from them?


Thanks.

I think the biggest concern would be the plastic warping & cracking in the delivery units just above the fusing units. Also the frame that the fuser mounts to becomes brittle over time and can cause problem with the mounting points. Sharp made changes in the follow up 257 & 317 models that addressed this problem. If they are new machines that were found in a warehouse, that won't be a problem right away. If they are used machines, there are modifications available for the mount point issue that helps some. Other than that, they have been reliable machines for us.

They are decent machines as far as I am concerned. The only thing I would do some checking in to is how long sharp expects to supply parts for them.

Great little machines. Absolute work horse.

The only thing i'd be worried about is the parts supply as posted above. Many of the parts will be backwards compatible with the ARM257 which was the replacment machine.

The series started as
AR235/275
AR237/277
AR257/310
MXM260/310 (current model)

Drum AR271DR is unique to this series and may no longer be produced in the next 2-5 years.
Charger AR270NC has been substitued to MX311NC which is the current model (MXM260)
Blade AR270BL has been subsituted to MX311BL which is the current model (MXM260)
Toner AR310NT was shared with the ARM257 which is discontinued but should have at least 5 years left
Fuser AR272FU These are dirt cheap, like 50 bucks. You can't even rebuild it for that. Im not 100% sure if you can substitue the AR310FU (ARM257) but i think it will work. The down side is the AR310FU is 3x the cost.
Transfer Kit AR272KA I don't think there is any difference from the ARM257 or the MXM260. Around 200k copies the little gear on the transfer unit gets chewed up pretty bad and can need to be replaced.
Drum Frame AR272DU Ive put a AR235 frame into a ARM237 and it works fine. I think it's the same as the newer machines but not 100% sure. The pins might be differnt.
Feed rollers AR310IR Same across the series.

As long as you change Drum, Blade, Charger, DV, these things will almost always go 75k copies no questions asked. Ive seen the fusers look like absolute shit and they don't double image but at 50 bucks a fuser i change em out when they look bad. We never used to replace the charger, just clean them. That would lead to a service call between PMs. Changing them out during PM times fixed that.

The fuser mount issue is a fairly easy fix. I think the very end of the line machines did have the mod applied before the ARM257 came out. Drill out the old holes and tape a metal back plate to the inside frame and use the proper metal screws and problem solved. The fuser gear on the drive pack was changed as it would get pointed and break down from the heat. New gear is cheap and very easy to change.

If they are dirt cheap and you can get the parts i'd do it.

Being a Sharp tech for the last 12 years or so, and having been to the school on the first models, the AR-235/275, the improved 237/277 is a great machine, like Lawrence said, do the mods, if needed, replaced PM parts as needed, change out delivery frames, if needed, they are a good running machine, and if you dont replace fuser unit, they are not hard to rebuild.

Tech bulletin listed LPLTM0388QSZZ for the metal backing plate, LX-BZ0079QSP1 for the screws to mount the fusing unit to that plate

When you do this fuser mod be sure to remove the drum unit. Plastic filings can drop into the drum unit when you drill the new holes in the plastic!

The AR-M208 belongs in that list somewhere, doesn't it?

Canada never sold the ARM208 but it's the same machine as a 235/275 by the looks of it.

The Leopard series (AR-235/275) was the earliest.
The Gazelle (AR-M208N) is the predecessor to the Andromeda series (AR-M237N/M277N) but very closely related.
I don't know the name for the more recent series AR-257/317

The main problems I experienced were delivery units crumbling, and dumping developer on this series. Most of the time a drum replacement stopped the pulling of developer.

Also cracking of the screw holes for the plate that gets removed for tray one feed roller replacement. Requires whole lower frame replacement.
