Using larger 775ml ink cartridges in the 115

HP Latex 100 Series

#1 rabtech 9 months ago

I am looking at the 400ml and the 775ml cartridge and Im trying to figure out what I cant use the 775ml that is used in the 300/500 in the 115.

Am i missing somthing>?

I need access to a lot more ink and the 400ml is just to small.

Unfortunately that is a limitation of this model Printer. You would have to change/upgrade to a Latex 315 model or higher to utilize the larger ink cartridges.

I have wondered what the actual limitation is. Is it a software issue? The cartridges look like they will physically fit. Will the machine just not recognize the 775ml cartridge?

I am curious as well. I need to order one and take a look at it. I need more ink than the 400ml. And I cant justify buying a 300 or 500 latex printer.

The 775ml ink supplies are not compatible and will not be made compatible with the 100 series latex printers. This is a design choice .

There's a lot of good choices you can make with your 775ml Ink Cartridges. Search your favorite ink and toner here.

why is there an expanded slot on the 115 if it has no use???

Hello @JLambert6517

I am afraid it has no use. This is a design choice.

#9 So if i purchase the 831 ink instead of 821 it wont work? yet it uses an 831 maintenance block.? Ide like to hear from someone at HP on this. Seems like a Bad choice to not make them universal and im wondering why would HP make this choice if it is true. Because it just doesn't make sense unless this was a design oops.

Hello JLambert6517!

The slots can support big carts, the FW cannot do it, so definitely this unit cannot use 775ml.

hello: when do you think an FW update is possible so that 775ml cartridges can be used?

#12 Hi, i belive is not going to work with FW update to support 775ml ink, the sku is set. only HP able modify it. just like HP-Sonia mention, is design choice.

I asked this question earlier on the site. HP didn't make a way for it to be compatible.
