For Lot 1, several thousand orders per year must be expected. In the old contract, 18,685 orders were placed. The bidder is free to offer original products from the respective manufacturers. This could be necessary, for example, if there are no alternative manufacturers for a particular product. If brand names are mentioned, equivalent products from other brands can also be offered. Both - original products (ink or toner cartridges from the original manufacturers of the corresponding printers) and - compatible products (complete replicas of original ink or toner cartridges) or - remanufactured products (used modules that are refilled after being collected, cleaned, tested, repaired or supplemented) are permitted. The contents of the toner cartridges offered must enable at least the page yield of the original toner cartridges. The contents of the ink cartridges offered must at least correspond to the contents (in ml) of the original ink cartridges. These "new products" are products that are comparable to the services described or are products that are not yet available on the market, that expand the range of services and are required to achieve the purpose pursued with the tender. These are exclusively toners, inks, drums, etc. from printers that are new to the market within the framework contract term or are new to the catalog of the HZD's standard printer range. To a small extent, these could also be toners, inks, drums, etc. from printers whose existence in the state of Hesse was not known to the awarding authority when the service description was drawn up. In this respect, this is an update of the framework contract during its term. The volume of these "new products" is estimated at around 20% of the total volume. The prices for these "new products" are based on a flat-rate, percentage surcharge by the bidder on their purchase price, which can be found on the price sheet in the "new products" register. Refill products, which are only refilled with toner or ink and are not subjected to quality assurance reconditioning (i.e. cleaning, testing, repair or addition of components), may not be used.

Several hundred orders per year must be expected for Lot 2. 3,416 orders were placed under the old contract. The bidder is free to offer original products from the respective manufacturers. This could be necessary, for example, if there are no alternative manufacturers for a particular product. If brand names are mentioned, equivalent products from other brands can also be offered. These "new products" are products that are comparable to the services described or are products that are not yet available on the market, that expand the range of services and are required to achieve the purpose of the tender. This only includes CDs, DVDs, BDs, empty cases, magnetic tapes, labeling tapes, cleaning materials (cloths, cleaning fluid, compressed air spray, etc.), fine dust filters, etc.) that are new to the market within the framework agreement term or are newly included in the catalog of the standard offer of the Hzd. In this respect, this is an update of the framework agreement during the term. The volume of these "new products" is estimated at around 20% of the total volume.

The lot expressly includes all successor products and future new products in the respective product groups. The pricing of future new products is based on a bidder's mark-up on his purchase price, which is requested and - based on an estimated (€) volume - assessed. With regard to the volume for lot 3, the Johann Wolfgang Goethe University assumes the following requirements: Brother toner: 1,694 toners Lexmark toner: 1,056 toners The requirement for HP ink / plotters is so low that the total turnover does not make up a significant part of the total turnover.
