I'm trying to determine which lamp is the sub and which is the main. There's no wattage stamped on them. I did see 1256 & 1265 stamped on them, but they don't cross reference to anything. Thanks.

Re: AR-M237 Fuser lamp indentification?
The simplest way to tell is where the tightest coils of the lamp element are positioned.
Main: Tightest coils toward the center
Sub: Tightest coils toward the ends
If the parts illustration is correct, the sub (RLMPU0027QSZZ) is on top, with the lamp "nub" closer to the front.
The main (RLMPU0026QSZZ) appears to be on the bottom, with the "nub" closer to the rear.
Does that help? =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

FYI Blackcat - The numbs are in the same place. They do look different in the parts guide though. Thanks again.Comment

Re: AR-M237 Fuser lamp indentification?
It was a good idea to look for the lamp wattage. Sharp isn't always very helpful in that respect though.
You didn't ask the next obvious question: How do you tell where the coils are densest if the lamp is opaque/frosted?
Just wipe down the lamp with alcohol. Frosted lamps become transparent when wet, and alcohol will not harm a halogen lamp.
This is how we used to confirm a bad halogen exposure lamp. It will meter infinite resistance of course, and show the silvery rings inside the quartz jacket (tungsten leaving the element), and maybe even see arcing at the lamp terminals, but you can also see the break in the element. Most MFP's these days use fluorescent or xenon or LED lamps which rarely need to get cleaned (or replaced), but on the early analog machines the super hot halogen lamps would collect airborn toner and have to be cleaned, usually with something fairly harsh like trichlorethylene then rinse off any residual oils with alcohol. The moving tabletop machines were known for this.
It was a surprise the first time I cleaned one of those lamps and noticed that they become transparent when wet. =^..^=If you'd like a serious answer to your request:
