My short question is... how much does an empty Epson SureColor P800 OEM cartridge weigh?

p.s. I called Epson support, but they don't know the answer, so hopefully one of you knows.

---End of short question---

If you are curious why I'm asking, here's the long explanation:

After printing with two 3800s for many years, I purchased an Epson SureColor P800 about 2 months ago. I installed the "Initial" carts and knew from experience to prevent clogs by printing "regularly". I have been printing a photo at least every 3 to 5 days, although sometimes I've printed several days in a row and/or several prints in a day. However, I don't go over 5 days without printing.

Then the other day, I was printing banner-style from a roll. Halfway through the first print, the colors were suddenly "off" meaning that the pinks were lacking. (So this was not a double-color management issue or wrong profile issue.) The next print with blue skies was very greenish and the next print with oranges printed very faint. I cancelled the print and did a nozzle check which showed all 100% dashes *except* for VLM which had absolutely NO dashes. Completely blank!

The printer's Ink Level diagram on the LCD thinks I have plenty of ink in all colors, with the PK and VLM about the same. However, the PK cart weighs 106 g and the VLM cart weighs only 64 g, which is 42 grams less than the PK cart. All of the other carts weigh between 106 and 118 g. I am still using the original "Initial" OEM carts.

Based on the Ink Levels diagram and the fact that the low ink indicator never triggered, it seems odd the VLM cart is so lightweight. Also, I have been printing a variety of photos with colors across the board... not heavily toward magenta.

FWIW, the Usage History Sheet says I've printed 72 "A2 Equivalent Prints".

When I called and emailed Epson Support, they said I must have a clog and should run a cleaning. However, I do not want to run a cleaning if the cart is empty. They did admit that I could damage the Epson P800 if run without ink. So that is the reason for my question. I don't want to clean with an empty cart and ruin my 2-month old printer.

Scan, crop and post your nozzle check.

Based on your story, it seems unlikely that a complete "clog" developed in the middle of a print. More likely is lack of ink.

I do appreciate your curiosity and hope you get the answer you want. Still, you should insert a new cartridge and perform a nozzle check. Hopefully you will be back to printing. If not, then proceed to the cleaning recommended by Epson, redo a nozzle check and post here. Compare nozzle checks to see if any progress occurs.

stratman, thanks for your reply. OK, attached are
1) a photo of the ink levels shown on the printer's LCD and
2) the nozzle check. I also wrote the weight in grams for each cart.

I ordered a new VLM cart and it's on the way, but I won't get it until Saturday.
