Nazalost ti kertridzi se ne pune. Kertridzi 36 i 37 nisu "punjivi". Kertridze koje moras da kupis moraju da imaju slovo A pored broja kertridza(36A i 37A) i jnih mozes da punis bez ikakvih problema. Problem je naci kod nas te kertridze, ali probaj kod malo jacih kompjuterskih firmi i mozda jos veci problem sto ce cena ta dva kertridza biti skoro ista koliko si platio i stampac.
Lexmark offers for sale two different versions of the same cartridge:
The regular version #36 and #37 is not refillable. It is the "Return Program" or "Prebate" cartridge. Supposedly, when you buy this cartridge you agree to return the empty cartridge to Lexmark. In return, Lexmark gives you roughly $5 off the retail list price of the cartridge.
The "A" version #36A and #37A can easily be refilled. However, the price of the cartridge is roughly $5 higher than the regular version, so most people unknowingly buy the regular version.
If you want to refill, you will need "A" version cartridges
