The brand of supplies you purchase is your decision. You are not required by any machine manufacturer's warranty to use only its brand. Premium Recharge cartridges are manufactured and guaranteed to work within the tolerances and specifications of your machine. If you buy re-manufactured cartridges from someone else, you might get poor service from your service technician. Of course the service technicians would like you to use the O.E.M. brand of re-manufactured cartridge they carry.
Some technicians do make commissions from the sale of supplies.
But, the choice is yours. A good service technician still wants your service business and should respect your choice of supplies. If you don't find the discount ink Cartridges that you are looking for, feel free to contact us for assistance.
