AR-M350 L6-10 code

MFP-TB-001..PDF

Based on the other copytechnet posts for this code I'm considering replacing the entire laser unit. Many people only replace the polygon mirror motor assembly. Thoughts? The Sharp tech bulletin MFP-TB-001 seems to indicate that only the polygon mirror motor needs replacement.

I personally have always replaced the assembly, and had 100% success. It is my understanding that the guys that replace the polygon mirror motor only discover that about 1/3 of those laser units have some other problem. =^..^=

The whole assembly is only $170.00. For that price I think I'll go with Blackcats advice and replace the LSU but thanks for replying my friend.

Ok....thought I'd post pics of the L6-10 repair for other techs .

Here is the Arm350 with mail bin assy. To get to the laser the mail bin assy must be removed.

At the rear the two securing screws at the bottom of the mail bin must be removed also.

Then you can carefully pull out the bin assy and set it aside

Now you can get at the right side cover and remove it.

Now your inside and need to unplug the connecters on the board below the laser and remove the 4 screws that secure it.

I just swing it out to the right so I can get to the fan and internal plate that you need to remove next.....

Then pull out the laser. Now your almost done.

Install the new LSU and carefully reconnect all the connectors and reassemble the copier. If all goes well and it fires up without the code ....... Ya did Gr8.

Hope this post helps someone in the future.

Re: AR-M350 L6-10 code

Without the mailbin it's a 10 minute job (especially if you scribe the slotted hole on the laser, for optical skew). Maybe 1/2 hour with the mail bin or AR-FN6.

There were some early production machines that it's considerably more difficult to pull the laser. The metal plate the fits around the laser didn't always come out quite so easily. Those early machines took 3 hours or more, with practice. =^..^=

I know.....Some of the arm280's were like that. Lol. Removing the mail bin wasn't too bad but you have to be careful with it or you can break off some of the plastic pieces....
