If the page yield of compatible toner cartridges is within 5% less than OEM’s, this is normal as page yield doesn’t just depended on how many toner is filled, but also affected by environment/the state of printer/prints coverage/print quantity/concentration setting etc. If less than OEM’s dramatically (more than 5%), there may be several reasons: a.The filled toner is not enough. Usually it will happen rarely, because we have strict quality control before delivery.  b.The document print is with high coverage. As most users print more graphics, gray scales and large amounts of text which with high coverage, obviously the page yield will not be enough.
Please check whether the sealing tape is pulled out if the blank page is printed. If the door inside the printer does not open, the laser bean cannot reach the OPC then there will no discharge on OPC thus no toner powder will be transferred. A broken OPC shutter door will stop image to be transferred from the OPC to the paper.
