[Misc] ARM237 sporadic lines across portrait page & maintenance required

[sbtiti]

When I produce a copy, with or without any content, the page comes out with horizontal thin lines that mostly do not go clear across the page. They never seem to be in the same place on multiple copies.

I am new to Sharp service and not understanding the service manual well. The copier states: "Maintenance Required". My question is what service or maintenance do you think would resolve this issue of lines? Is there a way to determine what maintenance has already been done?

NOTE: The paper is printed in a landscape mode or the leading edge is the widest if that makes any sense. It has a new fuser so that is not an issue.

Thanks,

Newbie Tech

likely to be charge corona grid needs cleaning or replacing. this produces random smokey lines lengthwise on A3/ledger paper

I'm sorry, but that statement does not make sense to me. Landscape mode has the shortest side as the lead edge, whether 8.5x11R, 8.5x14. or 11x17; portrait mode has the longest side as lead edge.

On some high end machines, I have seen long edge first as the lead edge (11x17); I know one of the older Sharp SD models did this.

For starters I'd recommend reading the part of the manual about doing the Preventative Maintenance. Most likely it will solve a lot of your problems.

What have you done so far? Anything? =^..^=

Sorry, I am not very good at technical writing. The paper is 8.5 X 11. It is fed into the copier sideways or 11" side goes in first. The original goes through the same way. When you look at the copy that comes out: The lines are thin and just a little fuzzy or smokey and sometimes appear to be in bold and then drop to fine or faint 2/3 the way across the page. Looking at the page in a portrait position the lines go from right to left.

It makes me wonder if the cleaning blade for the drum has a pinhole imperfection but they don't always show up in same location on the paper, although a few pages did have one line in the same spot. Most pages had 2 to 4 lines going across. Sometimes the line would be bold then fade to very faint then get bold again.

I was hoping the maintenance would resolve the issue, but I am not sure where to start after looking at the maintenance table and checking the page count do I need to replace all the parts listed for replacement under that number of pages? This copier is at our church and I am just trying to help them get it working better so we need to keep the expense as low as possible. Thank you for any assistance you can give me.

Sounds like the Main Charge corona. Replacing it will resolve. You can use the supply item MX311NC or AR310NC.

Re: ARM237 sporadic lines across portrait page & maintenance required

All you need to do for that type of line is clean the charge unit inside the drum assembly. Remove it, brush away any loose toner. Remove the grid and place it on a hard surface. Sprinkle a little windex on it and scrub with a soft brush. (both sides) Dry and reassemble.

But you really should also replace your drum, blade and developer to avoid problems down the road.

You're not doing anyone any favors by going the cheapskate route. Today I'll replace the primary. Tomorrow I'll change the developer cause it's dumping. The next day I'll change the drum, The day after that maybe I'll change some feed rollers.

You can successfully change (1) two hour call into (5) one hour calls. And how does that benefit anyone? Unless of course you won't take responsibility for your work, and bill for all these visits, then you benefit financially.

Please give this some thought. =^..^=

With the symptoms showing up on a copy, I would also clean the optics. I once had a bug on the mirrors and the little bugger would move around causing lines in random places. Just about did my head in.

DO THE PM or you'll just have to keep going out there for the same issues time and time again!!!!!!!!!!!!!!!!

Thanks, that sounds like a good plan. When you say replace the developer: what does that entail? You are not talking about the entire developer unit, are you?

Re: ARM237 sporadic lines across portrait page & maintenance required

It looks like I have bored everyone and they are done trying to help such a dummy! I purchased the service manual for this machine, but am having trouble with its methodology as compared to HP manuals I am used to using. I think I understand how to proceed except for the "Developer". At times I think the PM procedure is talking about the toner or developing powder and then it appears that it is saying to replace the Developing Unit or hopper/tank.

Can someone please clear this up for me? If I am to replace the powder do I need to dispose of the developer that is in the hopper or just add to it? The developer tank seems kind of pricey to replace every 75K pages. I would appreciate any help, thank you.

Most of the content here is aimed at technicians, specifically individuals that have some basic skills. From what I've read so far you do not have any background in laser printing, or even the most basic skills.

Do you realize that we bill $150 per hour to perform these tasks? Do you really expect us to train you to do it for yourself for nothing, from scratch? The manuals are not perfect, but you can figure it out for yourself if you read carefully.

Personally, I will help certain endusers that really make a serious effort. When I see that effort I'll jump right in. =^..^=
