Can I laser print on top of already laser printed pages?

[OMD-227]

exactly.

On those small laser printers, many of them have a film plastic fuser upper roller and a rubber lower roller (mainly because its cheap to manufacture and they dont last forever.... forcing you to spend money on another one or repairs).

There are many different fuser designs including film, aluminium, belt, rubber........all having different capabilities and costs. The SOHO stuff like your machine is made cheap, so it has some limitations, but printing what you want to do will work fine. I'd be very surprised if it didnt, but the only thing you'll get is a ghosting issue if anything, not damage to the fuser rollers.

The biggest problem I've seen with this issue is when someone prints some of the image on a full color MFP (with a 160C fixing temperature), than tries to re-run those same pages through a different B&W MFP (with a higher 190C fixing temperature). Some of the first image transfers onto the fuser rollers causing ghosting of the original color image. Also the second pickup causes a 35mm wide smudge, where the MP separation pad smears some of the first image at the leading edge on the back of the page, and continues to transfer it to subsequent pages. That's why copier manufacturers came up with automatic duplexing. The MP tray rollers and pad can be cleaned, but will continue to pickup toner residue from previous images. It's unavoidable. =^..^=

Thats the main point I have been trying to get across. The same machine should have little to no problems, its when a different machine type is used for each pass.
If the machine in question has a separation roller instead of separation pad there will be less issues too.

What is the reason for all this long discussion, have you forgotten that every machine works the way its manufacturer desired-n-designed it to perform. I believe that, are the machine specs which rules what to, and what not to do with a particular model. In the specifications you'll find overlays, OHP, card printing etc. In fact when you go looking for a new printer, you consult the specs to determine which model fits your particular requirements!

In a perfect world, yes.

But in the world we live in, the salesman promises, or the buyer imagines that a machine may be suitable, then they put the responsibility onto the tech to live up to these imagined criterion. Read the specs, or an operators manual? Are you mad? This guy is a printer and had no concept of the media types or variable meaning of the lb designation. He does the majority of his printing on a $95 inkjet.

Or the machine proves perfectly suitable for the initial criterion. Now why can't we print onto those spare chunks of particle board? And why not? Wood is like paper, sort of. This guy wants to buy a $700 color MFP to do the same tasks as a $15K to $20K full sized machine. Sorry! That $14K difference is price means major differences in the machine. Who'd a thought? =^..^=

Store websites very often have bad specs on their site and even on the labels they print under the products. In fact, for my MF8350Cdn, the spec sheet in the shelf printed by the store clearly says it does double sided scanning (then again, they probably like me thought if the $200 inkjet next to it does it, this $800 laser must do it, but it doesn't). But I had read the specs on the Canon site before buying as well as reviews so I knew it didn't do double sided scanning but with the $350 discount there was on it it was worth it (double sided printing is what's most important to me).

I did know what lbs rating means, I've been running a printing service for over 5 years, it's the g/m2 ratings I didn't know much about as they are rarely used.

And my inkjet is $700, not $95, a $95 inkjet could never have printed 250 000 prints and still work, not to mention it certainly wouldn't be 35 pages/minute like my $700 inkjet.

About reprinting the sheets a 2nd time this was for a project that I thought of 2 days ago, and finally I decided to put a colored background on the cards so I will have to print the card ID codes with the design itself as the codes are white against a black background.

When you buy specialized equipment on general-purpose stores, where salespeople usually have only a slight grasp of what's being sold, it's not unusual for the specs to be erroneous at best or totally wrong at worst.
